TECHNICAL FIELD

The present invention relates to a lid for a flowable substancecontainer. More specifically, the present invention relates to areclosable lid for use with a drink container.

BACKGROUND OF THE INVENTION

Lids for containers are well-known in the beverage container industry.In general terms, lids for single-use or disposable containers havethree main components: a top wall or surface, a mounting portion, and anopening. Typically, the mounting portion is adapted to engage an upperrim of the container to seal the lid on the container. The opening isadapted to permit the flow of the container contents through the lid.

Existing lid designs suffer from a number of problems including untimelyspillage through the opening due to the lack of a reliable means forsealing the opening. The inability to effectively seal the opening canalso result in a significant loss of heat from the container contentsthrough the opening. To address these and other problems, a number oflid designs include a movable cover portion for the opening. However,most existing movable covers lack structural integrity and as a result,do not effectively seal the opening. Also, a number of movable coversare difficult to operate due to their complex design. In addition, avast majority of movable covers interfere with a user consuming thecontainer contents through the opening.

U.S. Pat. No. 4,579,245 to Narushko provides an example of a containerlid with a movable closing flap. The lid has a raised segment that formsa channel, which is adapted to receive the closing flap. The closingflap is a curved piece that must be inserted into the channel. Theclosing flap is movable between an open position and a closed position.Because the movement of the closing flap is controlled by a series ofnotches, grooves, tabs and handles located on the channel and theclosing flap, the closing flap is difficult to operate and theeffectiveness of the lid is compromised.

Another example of a lid having a movable cover for the opening isdisclosed in U.S. Pat. No. 4,790,444 to Terzi. There, the hood or lidhas an opening formed from a depending spout that is inserted into thecontainer opening. The cover has exterior dimensions equivalent to thelid and is placed over the lid. The cover has an opening that must bealigned with the spout and the lid opening to form the drink passageway.The cover has a plurality of sockets, which when properly aligned, sealthe lid opening. The cover is supported on the lid by a series ofintricate structures and an annular gasket. Due to its complex array ofstructures, the lid and cover are difficult to assemble and operate.Furthermore, the array of structures can inhibit the alignment of thelid opening and the cover opening negatively affecting the formation ofthe drink passageway.

Therefore, there is a definite need for a reclosable container lid thatreliably seals the opening. In addition, there is a need for such a lidthat is easy to operate and does not interfere with a user consuming thecontainer contents through the opening.

The present invention is provided to solve these and other problems.

A reclosable lid 10 for a container (not shown) of the present inventionis illustrated in FIG. 1. The container has a central opening defining avolume that can be used to hold or contain a flowable substance, forexample a liquid or a powder. The container and the lid 10 can be ofeither the disposable or extended use variety. FIG. 1 shows the lid 10in the closed position wherein the lid 10 is sealed such that theflowable substance cannot flow through the lid 10. The lid 10 generallyhas a first piece or cover 12, and a movable second piece or disk 50(positioned underneath cover 12 in FIG. 1).

The cover 12 of the lid 10 is adapted to span the opening in the upperportion of the container that is generally defined by an upper rim oredge of the container. For illustrative purposes, the container could bea coffee cup having an opening defined by the rim of the cup.

The cover 12 has an annular top wall 14 and a side wall 16 dependingfrom a peripheral edge 18 of the top wall 14. Although the top wall 14is shown as having a generally flat upper surface 14 a, the uppersurface 14 a can be curved or angled. The side wall 16 has a side wallsurface 16 a and a lower edge 20. The side wall surface 16 a can becurved or generally flat. The overall shape of the cover 12 is generallyfrustoconical, however, the cover 12 can have a number of otherconfigurations.

A mounting portion 22 depends from the lower edge 20 of the side wall16. The mounting portion 22 includes a generally annular flange 24 and agenerally annular skirt 26. The mounting portion 22 is adapted forconnecting the lid 10 to the container in a manner that seals the lid 10on the container. Thus, the mounting portion 22 prevents leakage of thecontainer contents between the lid 10 and the container when the lid 10is positioned on the container. In a preferred embodiment, the mountingportion 22 is integral with the side wall 6.

An aperture or drink opening 28 is located preferably in the top wall14. Alternatively, the drink opening is located in the side wall 16. Theopening 28 is adapted to permit the passage or flow of the flowablecontents held by the container through the cover 12. The opening 28 hasan edge 29 that defines the shape of the opening 28. Although shown inFIG. 1 as having an obround shape, the opening 28 can have a variety ofshapes, including but not limited to circular, square, or rectangular.In the closed lid position shown in FIG. 1, at least a portion of aprojection 52 of the disk 50 is received by or positioned in the opening28. Alternatively, the disk 50 has a generally planar surface that isaligned with a surface of the cover 12 proximate the opening 28 in asurface-to-surface engagement such that the opening 28 is sealed. Theseaspects will be described below in greater detail.

A slot or channel 30 is located preferably in the top wall 14. The slot30 has an edge 32 that defines the shape of the slot 30. Although shownin FIG. 1 as having an obround shape, the slot 30 can have a variety ofshapes, including but not limited to circular, square, or rectangular. Apost 54 extends from the movable disk 50. The slot 30 is adapted toreceive at least a portion of the post 54 extending through at least aportion of the slot 30. Described in a different manner, at least aportion of the post 54 extends past the top wall surface 14 a. Thisaspect will also be described below in greater detail.

Referring to FIGS. 1 and 2, the cover 12 further comprises at least onesupport member 34. The support member 34 has a peripheral edge 44 thatdefines the shape of the support member 34. The peripheral edge 44 hasan upper edge 44 a and a lower edge 44 b. The peripheral edge 44 canhave a variety of shapes, including the linear shape of the upper edge44 a and the serrated shape of the lower edge 44 b. A cavity 46 isrecessed from the peripheral edge 44. Described in a different manner,the cavity 46 extends radially inward from the peripheral edge 44. As aresult, at least a portion of the support member 34 extends radiallyinward past an inner surface of the side wall 16. The dimensions andconfigurations of the support member 34 and the cavity 46 can vary withdesign parameters, including but not limited to the overall size of thecover 12 and/or the size of the movable second piece 50. The position ofthe support member 34 can also vary along the height of the side wall16. For example, the support member 34 can be positioned proximate theperipheral edge 18, or the support member 34 can be positioned closer tothe mounting portion 22.

FIG. 3 shows an interior cavity of the lid 12. At least one internalsupport ledge 102 is positioned on an internal surface 100 of the cover12. The support ledge 102 is formed from the material defining thecavity 46 of the support member 34 which extends radially inward fromthe side wall 16. Accordingly, the material that forms the cavity 46also forms the internal support ledge 102. The support ledge 102 has anupper edge 102 a. Although shown having an elongated configuration, thedimensions and configurations of the support ledge 102 can varydepending upon the configuration of the support member 34 and the degreeto which the support member 34 extends radially inward. The role of thesupport ledge 102 is fully described below.

As shown in FIG. 1, a center portion 36 is positioned radially inwardfrom an inner edge 38 of the top wall 14. Preferably, the center portion36 is recessed such that the center portion 36 has a curvilinearconfiguration when viewed in cross-section. The degree of recess orcurvature of the center portion 36 can vary with the design parametersof the lid 10. Alternatively, the center portion 36 is in planaralignment with the top wall 14. In this configuration, the centerportion 36 is not recessed.

Referring to FIGS. 1 and 2, the side wall 16 has a recessed portion 40,that is adapted to receive a lip of a person drinking from thecontainer. An edge 42 of recessed portion 40 defines the configurationof the portion 40. In a preferred embodiment, the edge 42 has agenerally straight base portion 43 that connects with a generallyoutwardly curved end segment 45 at each end. The recessed portion 40 ispositioned radially inward from the side wall surface 16 a. Although therecessed portion 40 is shown positioned on both the top wall 14 and theside wall 16, the recessed portion 40 can be limited to either the topwall 14 or the side wall 16. The shape and configuration of the recessedportion 40 can be varied to conform to numerous design parameters.Similarly, the degree of recess of the portion 40 can vary. For example,as shown in FIG. 1, the recessed portion 40 is deeper at base portion 43and shallower at an end proximate the drink opening 28. Preferably, therecessed portion 40 is positioned about the drink opening 28. The topwall 14 and the side wall 16 cooperate to form a rounded edge 40 b atthe recessed portion 40.

Referring to FIG. 3, an internal support edge 104 is positioned in theinternal surface 100 of the cover 12. The internal support edge 104 isformed from the material defining the recessed portion 40 which extendsradially inward from the side wall 16. Accordingly, a portion of thematerial that forms the recessed portion 40 also forms the internalsupport edge 104. Preferably, the support edge 104 is positionedinternal to and coincident with the rounded edge 40 b of the recessedportion 40. The dimensions and configurations of the support edge 104can vary depending upon the configuration of the recessed portion 40 andthe degree to which the recessed portion 40 extends radially inward. Therole of the support edge 104 is fully described below.

A side wall 59 dependsfrom the outer shoulder 58. A center portion 62 extends radially inwardfrom the inner shoulder 60. The center portion 62 comprises an annularside wall 64 and an inner portion 66. Preferably, the center portion 62is recessed such that the center portion 62 has a curvilinearconfiguration when viewed in cross-section. The degree of recess orcurvature of the center portion 62 can vary with the design parametersof the lid 10. Preferably, the degree of recess of the center portion 62of the disk 50 is similar to the degree of recess of the center portion36 of the cover 12. Alternatively, the inner portion 66 can be removedfrom the center portion 62 to reduce the weight and/or cost of the disk50. In this configuration, the disk 50 has a ring-shaped configuration.

The projection 52 extends from a portion of the top wall 56. Theprojection 52 has a peripheral edge 68 that defines the shape of theprojection 52. Preferably, the projection 52 is cooperativelydimensioned with the drink opening 28 such that at least a portion ofthe projection 52 is adapted to be received by or positioned in theopening 28. The projection 52 has a projection surface 52 a that ispreferably sloped or angled to facilitate reception of the projection 52by the opening 28. When the projection 52 is completely received in theopening 28, the opening 28 is sealed and the lid 10 is in the closedposition shown in FIG. 1. In the closed position, a top portion 70 ofthe projection 52 extends past the recessed portion surface 40 a.

The post 54 extends from a portion of the top wall 56. As shown in FIG.4, the post 54 has opposed end walls 72, opposed side walls 74, and atop wall 76. The post 54 can have either a solid or hollow constructiondepending upon design parameters. At least a portion of the post 54 isreceived by the slot 30 and extends past the top wall surface 14 a.Although the configuration and dimensions of the post 54 can varyaccording to design parameters of the lid 10, the post 54 must retain aconfiguration that permits it to be received by the slot 30. As shown inFIG. 4, the post 54 has a catenoid shape. The post 54 can have agripping portion (not shown) that is adapted to facilitate theengagement of a user's fingers with the post 54. The gripping portioncan be integral to the post 54 or it can be a separate element fastenedto a portion of the post 54. For example, the gripping portion can be aplastic or rubber element fastened to the walls 72, 74.

As shown in FIG. 4, the disk 50 has at least one aperture 78. Theaperture 78 has a peripheral edge 80 that defines the shape of theaperture 78. When the aperture 78 is aligned with the drink opening 28,a passageway is formed between the disk 50 and the cover 12 permittingthe passage or flow of the flowable substance held by the containerthrough the lid 10. Although the aperture 78 can have a variety ofconfigurations and dimensions, the aperture 78 is preferablycooperatively dimensioned with the drink opening 28. In a preferredembodiment, the aperture 78 is positioned within the disk 50 recessedportion 84 and spaced a distance from the projection 52. In anotherpreferred embodiment, the disk 50 includes two separate apertures 78.

The disk recessed portion 84 is preferably positioned about theprojection 52 and the aperture 78. The degree of recess of the portion84 can vary. An edge 86 of recessed portion 84 defines the configurationof the recessed portion 84. Although the recessed portion 84 is shownpositioned on a portion of both the disk side wall 59 and the disk topwall 56, the recessed portion 84 can be limited to either the side wall59 or the top wall 56. The recessed portion 84 is adapted to be receivedby an inner surface of the recessed portion 40 of the cover 12 when thedisk 50 is positioned proximate the cover 12. Accordingly, the shape andconfiguration of the recessed portion 84 of the disk 50 is similar tothe shape and configuration recessed portion 40 of the cover 12. The topwall 56 and the side wall 59 cooperate to form a rounded edge 84 b atthe recessed portion 84.

As further shown in FIG. 4, the disk 50 has at least one well 90depending from a portion of the disk 50. The disk 50 has a first well 90a and a second well 90 b in one preferred embodiment. The well 90 candepend from either the top wall 56 or the side wall 59, or therebetween.The well 90 has an outer edge 92 that defines the general shape of thewell 90. A shoulder 94 depends from the outer edge 92. The shoulder 94can have a curvilinear portion 94 a and a generally linear portion 94 b.An inner wall 96 depends from the shoulder 94. As shown in FIG. 4, theinner wall 96 has a generally annular configuration resulting in agenerally tubular well configuration. However, the well 90 can have avariety of configurations depending upon design parameters. Preferably,the well 90 has a bottom wall (not shown). Alternatively, the bottomwall is omitted, causing the well 90 to have a hollow, tubularconfiguration.

The first and second wells 90 a, 90 b can be positioned at variouslocations in the disk 50. Preferably, the first and second wells 90 a,90 b are spaced a distance apart. The first well 90 a and the secondwell 90 b have the same dimensions and configurations. The depth orlength of the well 90, as measured from a lower surface (not shown) ofthe disk 50 can vary. Similarly, the number and dimensions of the well90, including the diameter, can vary with the numerous designparameters.

A drain hole (not shown) can be positioned in the disk 50, preferably inthe center portion 62. When the flowable contents, i.e., liquid,accumulate between an interior surface of the cover 12 and the disk 50,the drain hole ensures the drainage of such contents into the container.

Referring to FIG. 1, the disk 50 and the cover 12 are cooperativelydimensioned such that the disk 50 can be positioned within an interiorportion of the cover 12 to define an “assembled position.” Referring toFIG. 3, in the assembled position, the disk 50 is rotatably supported byat least one support ledge 102 which is formed by the support member 34extending radially inward as explained above. Specifically, a portion ofthe edge 51 of the disk 50 rotatably engages the support ledge 102. Thedisk 50 can be further rotatably supported by the interior edge 104 ofthe recessed portion 40. Although the cover 12 is shown in one preferredembodiment as having three support members 34 and three correspondingsupport ledges 102, the number and configuration of the members 34 andthe ledges 102 can vary with the design parameters.

In the assembled position, the disk 50 is positioned proximate the cover12 such that at least a portion of the post 54 is received by andextends through the slot 30. Described in a different manner, the disk50 is positioned beneath the cover 12 such that the center portion 36 ofthe cover 12 is proximate the center portion 62 of the disk 50.

In the assembled position, the disk 50 is movable between a firstposition P1 and a second position P2. In the first position P1, as shownin FIG. 1, the projection 52 is received by the drink opening 28 suchthat the opening 28 is sealed and the lid 10 is closed. When the opening28 is sealed, the edge 29 of the opening 28 is in frictional engagementwith the projection 52. The top portion 70 of the projection 52 canextend past the edge 29 of the drink opening 28. This seal prevents theflow of the flowable substance in the container through the opening 28,enabling the container and lid 10 to be moved without risking spillage.Also, in the first position P1, the recessed portion 84 of the disk 50is engaged with the recessed portion 40 of the cover 12. In addition, inthe first position P1, the aperture 78 is misaligned or offset from theopening 28. Alternatively, the projection 52 and the opening 28 are in asnap fit engagement wherein each have sufficient structure to enable thesnap fit engagement. Other cooperating structures can also be utilized.

In an alternate configuration of the disk 50, the projection 52 isomitted and the disk 50 has a generally planar surface (not shown). Inthe first position P1, the planar surface of the disk 50 is aligned withthe opening 28 in a surface-to-surface engagement such that the opening28 is sealed.

In the second position P2, a user engages the post 54 to rotate the disk50 wherein the aperture 78 is aligned with the drink opening 28 to forma passageway between the disk 50 and the cover 12 wherein the lid 10 isopen. The passageway permits the passage or flow of the flowablesubstance held by the container through the lid 10. When the lid 10 isin the second position P2, at least a portion of the edge 80 of theaperture 78 is aligned with at least a portion of the edge 29 of thedrink opening 28. Also, in the second position P2, the recessed portion84 of the disk 50 is misaligned or offset from the recessed portion 40of the cover 12. In addition, in the second position P2, the projection52 is misaligned or offset from the opening 28. When the aperture 78 ispartially aligned with the drink opening 28, the passageway remains butits dimensions are reduced. When the aperture 78 is completelymisaligned with the drink opening 28, the passageway is eliminated. Whenthe aperture 78 is completely misaligned with the drink opening 28 andthe projection 52 is completely received in the opening 28, the opening28 is sealed and the lid 10 is in the first position P1.

When the disk 50 is moved between the first position P1 and the secondposition P2, a portion of the edge 51 of the disk 50 remains inrotatable engagement with the support ledge 102. Accordingly, thesupport ledge 102 provides support to the disk 50 such that the disk 50remains in the assembled position during movement between the first andsecond positions, P1, P2. When the cover 12 includes a plurality ofsupport ledges 102, a greater portion of the edge 51 of the disk 50remains in rotatable engagement with the support ledges 102. The edge104 of the recessed portion 40 provides additional support for the disk50 as it is moved between the first and second positions P1, P2.

A user can move the disk 50 between the first position P1 and the secondposition P2 by grasping and actuating or manipulating the post 54between the first end 30 a of the slot 30 and the second end 30 b of theslot 30. Referring to FIG. 1, when the post 54 is proximate the firstend 30 a, the disk 50 is in the first position P1. Conversely, when thepost 54 is proximate the second end 30 b, the disk 50 is in the secondposition P2. The post 54 can be located in a number of positions betweenthe first and second ends 30 a, 30 b and as a result, the projection 52can be misaligned with the opening 28 to varying degrees.

The disk 50 can be rotated or moved a varying amount depending upon thenumerous design parameters of the lid 10, including but not limited tothe configuration and dimensions of the post 54 and the slot 30. Thus,the disk 50 assumes a number of positions and those positions dependupon the location of the post 54 relative to the slot 30. The movementof the disk 50 and the post 54 is ultimately constrained by the firstand second ends 30 a, 30 b of the slot 30.

The lid 10 is adapted to permit a user to move the post 54 between thefirst and second positions P1, P2 with only one hand. This means that auser can hold the container and manipulate the post 54 with the samehand. This increases the flexibility and the commercial value of the lid10.

As explained above, the disk 50 can have two separate apertures 78,wherein the apertures 78 are positioned about the projection 52. In thisconfiguration, the disk 50 can be rotated in either a clockwise orcounter-clockwise direction to move the disk 50 between the firstposition P1 and the second position P2. For example, rotating the disk50 in the clockwise direction brings one aperture 78 into alignment withthe opening 28, while rotating the disk in the counter-clockwisedirection brings the other aperture 78 into alignment with the opening28. This feature further increases the flexibility and the commercialvalue of the lid 10. In such configuration, the length of the slot 30 isincreased to allow for counterclockwise rotation of the disk 50 suchthat both apertures 78 can be aligned with the opening 28.

The lid 10 is adapted to be used without the disk 50. This means thatthe cover 12 is connected to a container but the disk 50 is omitted. Inthis configuration, there is no slot 30 and there is no structure toseal the opening 28 in the cover 12 and as a result, the flowablesubstance held by the container can pass through the lid 10. In thisconfiguration, the recessed portion 40 remains positioned on both thetop wall 14 and the side wall 16. However, the drink opening 28 can bepositioned in either the top wall 14 or the side wall 16.

The opening 28 can be formed with a range of dimensions. At a minimum,the opening 28 should have dimensions sufficient to permit the passageof the flowable substance held by the container and receive theprojection 52. The slot 30 can be formed with a range of dimensions. Ata minimum, the slot 30 should have dimensions sufficient to receive andpermit the movement of the post 54.

The opening 28 can be located at various positions along the top wall 14depending upon design parameters. Similarly, the slot 30 can be locatedat various positions along the top wall 12. The opening 28 and the slot30 are spaced a distance apart. Preferably, the opening 28 and the slot30 are opposed on the top wall 12, meaning that they are positionedapproximately 180 degrees apart. Alternatively, the post 54 is locatedon the sidewall 59 of the disk 50, and the slot 30 is cooperativelylocated on the sidewall 16 of the cover 12. In this configuration, auser moves the lid 10 between the first and second positions P1, P2 byengaging the post 54 that extends through the slot 30 positioned on theside wall 16 of the cover 12.

Although shown as having a generally circular shape, the lid 10,including the mounting portion 22, the flange 24 and the skirt 26, canhave numerous configurations. For example, the lid 10 could have arectangular, square, or oval shape. To ensure a leak-proof seal with thecontainer, the shape of the mounting portion 22 should match the shapeof the upper edge of the container so a cooperative sealing engagementcan be achieved.

Alternatively, the mounting portion 22 could have a shape similar to theupper edge of the container, yet dissimilar from the shape of the sidewall 16 and the top wall 14. For example, the mounting portion 22 couldhave an annular shape consistent with the container shape and the walls14, 16 could have a non-annular shape.

Unlike prior art designs, the dimensions and the configuration of theopening 28 are not affected by the engagement and disengagement of theprojection 52 as the disk 50 is moved between the first and secondpositions P1, P2. This attribute allows a user to repeatedly move thedisk 50 between the first position and second position. Accordingly, thestructural integrity and the durability of the lid 10 are increased.

The well 90 is adapted to aid in the storage and/or stacking of the disk50 prior to the disk 50 and cover 12 being placed in the assembledposition. Specifically, the well 90 is adapted to ensure that multipledisks 50 remain stacked in a stable vertical configuration prior toassembly of the lid 10. A portion of the well 90 of a first disk 50engages a portion of well 90 of an adjacent second disk 50 positionedbelow the first disk 50. Accordingly, the well 90 should have a depth orlength sufficient to permit it to engage a portion of the well 90 of thesecond disk 50. In an alternative configuration, the well 90 can berandomly placed wherein the well 90 of the first disk would rest on thetop wall 56 of the second disk 50.

The well 90 is further adapted to aid in the storage and/or stacking ofthe assembled lid 10. Specifically, the well 90 is adapted to ensurethat multiple lids 10 remain stacked in a stable vertical configuration.A portion of the well 90 of a first lid 10 engages a portion of anadjacent cover 12 of a second lid 10 positioned below the first lid 10.Accordingly, the well 90 should have a depth or length sufficient topermit it to engage a portion of the cover 12. The engagement of thewell 90 with a portion of the cover 12 stabilizes the first and secondlids 10 in their vertical position. The engagement of the well 90 with aportion of the cover 12 prevents the first and second lids 10 frombecoming destabilized and/or misaligned.

The lid 10 can be formed by a variety of manufacturing processes, suchas injection molding or a thermoforming operation, preferably vacuumforming and/or pressure forming. The cover 12 is preferably formed fromplastic, however, other lightweight materials can be used to form thecover 12. After the manufacturing process has been completed, the drinkopening 28 and the slot 30 may be formed in the cover 12 with a punchand die.

Preferably, the disk 50 is formed from the same material used to formthe cover 12. However, the disk 50 can be formed from other lightweightmaterials. After the manufacturing process has been completed, theaperture 78 may be formed in the disk 50 with a punch and die.

The lid 10 can include a color-based system for indicating the status ofthe lid 10. Under the color-based system, a portion of the lid 10 woulddisplay a first color, e.g., red, when the lid 10 is closed in the firstposition P1. Similarly, a portion of the lid 10 would display a secondcolor, e.g., green, when the lid 10 is open in the second position P2.The first and second colors would be displayed in a visible portion ofthe lid 10 such that a user of the lid 10 could readily ascertain thestatus of the lid 10. Referring to FIGS. 1 and 4, the first color ispositioned on the disk 50 to the right of the post 54 and the secondcolor is positioned on the disk 50 to the left of the post 54.Accordingly, when the lid 10 is in the closed position P1 shown in FIG.1, the first color is visible through the slot 30. Conversely, when thelid 10 is in the open position P2, the second color is visible throughthe slot 30. In this manner, a user can verify the status of the lid 10by simply looking at the color indicator displayed through the slot 30.As a result, the utility and marketability of the lid 10 is increased.

In an alternate color-based system configuration, the first color ispositioned on the projection 52 wherein it is visible when the lid 10 isin the closed position P1. The second color is positioned on the edge 80about the aperture 78 wherein it is visible when the lid 10 is in theopen position P2. In this manner, a user can verify the status of thelid 10 by simply looking at the color indicator displayed in the opening28.

FIGS. 5-8 disclose another preferred embodiment of the lid of thepresent invention. As shown in FIG. 5, the reclosable lid 210 generallyincludes a first piece or cover 212, and a movable second piece oroverlay 250. FIG. 5 shows the lid 210 in the open position wherein theflowable substance can flow or pass through the lid 210 via opening 228.

Referring to FIGS. 5 and 6, the cover 212 is adapted to span the openingin the upper portion of the container (not shown) that is generallydefined by an upper rim or edge of the container. The cover 212 has anannular top wall 214 and a side wall 216 depending from an outer orperipheral edge 218 of the top wall 214. Although the top wall 214 isshown as having a generally flat upper surface 214 a, the upper surface214 a can be curved or angled. The side wall 216 has a side wall surface216 a and a lower edge 220. The side wall surface 216 a can be curved,angled, or generally flat. The overall shape of the cover 212 isgenerally frustoconical, however, the cover 212 can have a number ofother configurations.

A mounting portion 222 depends from the lower edge 220 of the side wall218. The mounting portion 222 includes a generally annular flange 224and a generally annular skirt 226. The mounting portion 222 is adaptedfor connecting the lid 210 to the container in a manner that seals thelid 210 on the container. Thus, the mounting portion 222 preventsleakage of the container contents between the lid 210 and the containerwhen the lid 210 is positioned on the container. In a preferredembodiment, the mounting portion 222 is integral with the side wall 16.

An aperture or drink opening 228 is located preferably in the top wall216. Alternatively, the drink opening 228 is located in the side wall216. The opening 228 is adapted to permit the passage or flow of theflowable contents held by the container through the cover 212. Theopening 228 has an edge 229 that defines the shape of the opening 228.Although shown in FIG. 6 as having an obround shape, the opening 228 canhave a variety of shapes, including but not limited to circular, square,or rectangular.

The opening 228 can be formed with a range of dimensions. At a minimum,the opening 228 should have dimensions sufficient to permit the passageof the flowable substance held by the container. The opening 228 can belocated at various positions along the top wall 214 depending upondesign parameters.

As shown in FIG. 6, a center portion 236 is positioned radially inwardfrom an inner edge 238 of the top wall 214. Preferably, the centerportion 236 is recessed such that the center portion 236 has acurvilinear configuration when viewed in cross-section. Described in adifferent manner, the center portion 236 has a concave shape when theportion 236 is viewed from a point above the lid 210. The degree ofrecess or curvature of the center portion 236 can vary with the designparameters of the lid 210.

Referring to FIGS. 5 and 6, the side wall 216 has a recessed portion 240that is adapted to receive a lip of a person drinking from thecontainer. An edge 242 of recessed portion 240 defines the configurationof the portion 240. The recessed portion 240 and the recessed surface240 a are positioned radially inward from the side wall surface 216 a.Although the recessed portion 240 is shown positioned on both the topwall 214 and the side wall 216, the recessed portion 240 can be limitedto either the top wall 214 or the side wall 216. The shape andconfiguration of the recessed portion 240 can be varied to conform tonumerous design parameters. Similarly, the degree of recess of theportion 240 can vary. Preferably, the recessed portion 240 is positionedabout the drink opening 228. The top wall 214 and the side wall 216cooperate to form a rounded edge 240 b at the recessed portion 240.

As shown in FIGS. 5 and 7, the overlay 250 is a discontinuous structureadapted to be positioned about the cover 212. The overlay has a top wall252 and a side wall 254 depending from an outer or peripheral edge 256of the top wall 252. Although the top wall 252 is shown as having agenerally flat upper surface 252 a, the upper surface 252 a can becurved or angled. The side wall 254 has a side wall surface 254 a and alower edge 258. The side wall surface 254 a can be curved, angled orgenerally flat.

A mounting portion 260 depends from the lower edge 258 of the side wall254. The mounting portion 260 includes a generally annular flange 262and a generally annular skirt 264. The mounting portion 260 is adaptedfor rotatably connecting the overlay 250 to the mounting portion 222 ofthe cover 212 such that the overlay 250 and the cover 212 are inrotatable engagement. The mounting portions 222, 260 are cooperativelydimensioned such that the overlay 250 can be positioned about the cover212 wherein the overlay 250 can be rotatably moved with respect to thecover 212. The mounting portions 222, 260 have a generally annularconfiguration. Alternatively, the mounting portions 222, 260 could havea configuration with angular or linear segments.

Preferably the mounting portions 222, 260 have a continuousconfiguration, as shown in FIGS. 5-8. Alternatively, the mountingportions 222, 260 have a discontinuous configuration, meaning that theportions 222, 260 have material removed that results in a notchedconfiguration.

As shown in FIG. 7, the overlay 250 has a projection 264 that is locatedpreferably in the top wall 252. Alternatively, when the drink opening228 is positioned in the side wall 216 of the cover 212, the projection264 is cooperatively positioned in the side wall 254 of the overlay 250.The projection 264 depends from a lower or inner surface (not shown) ofthe top wall 252. The projection 264 has a peripheral edge 266 thatdefines the shape of the projection 264. Preferably, the projection 264is cooperatively dimensioned with the drink opening 228 such that atleast a portion of the projection 264 is adapted to be received by orpositioned in the opening 228. When the projection 264 is completelyreceived in the opening 228, the opening 228 is sealed and the lid 210is in the closed position shown in FIG. 8. In the closed position, abottom wall 268 of the projection 264 extends past the top wall surface214 a.

As further shown in FIG. 7, a center portion 270 is positioned radiallyinward from an inner edge 272 of the top wall 252. Preferably, thecenter portion 270 is recessed such that the center portion 270 has acurvilinear configuration when viewed in cross-section. Described in adifferent manner, the center portion 270 has a concave shape when theportion 270 is viewed from a point above the lid 210. The degree ofrecess or curvature of the center portion 270 can vary with the designparameters of the lid 210. Alternatively, the center portion 270 is inplanar alignment with the top wall 252. In this configuration, thecenter portion 270 is not recessed.

The overlay 250 has at least one gripping element 274 positioned on aportion of the side wall 254. The gripping element 274 is adapted tofacilitate rotational movement of the overlay 250. Accordingly, a userengages the element 274 to aid in the rotation of the overlay 250.Although shown as having a generally elongated configuration, theelement 274 can have a wide range of configurations and dimensions. Inaddition, the gripping element 274 can be positioned on the side wall254, the top wall 252 or on a portion of both the side wall 254 and thetop wall 252. Alternatively, the gripping element 274 is positioned on aportion of the mounting portion 260. The gripping element 274 can beintegral to the overlay 250 or it can be a separate element fastened toa portion of the overlay 250. For example, the gripping portion can be aplastic or rubber element fastened to the overlay 250.

The overlay 250 can have alternate structures for facilitating movementof the overlay 250. For example, the overlay 250 could have a post or aring extending from a portion of the overlay 250, each adapted for auser to engage and rotate the overlay 250.

As shown in FIGS. 5, 7 and 8, and as explained above, the overlay 250has a discontinuous structure, meaning that neither the top wall 252 northe side wall 254 are continuous along the circumference of the cover250. As a result, the overlay has a first side wall portion 254 b and asecond side wall portion 254 c. When the projection 264 is located in aportion of the top wall 252, the projection 264 is positioned proximateeither of the side wall portion 254 b or the second side wall portion254 c. Preferably, the gripping element 274 is positioned on the otherof the wall portion 254 b or the second side wall portion 254 c.Alternatively, the gripping element 274 is positioned on the side wallportion 254 b, 254 c proximate the projection 264.

Due to its discontinuous configuration, the overlay 250 has an aperture276. In one preferred embodiment, the overlay 250 has two aperture 276wherein the portion of the overlay 250 above the mounting portion 262has a generally hour-glass shape. The configuration and dimensions ofthe aperture 276 can vary greatly with the design parameters of the lid210. Referring to FIG. 7, the overlay 250 has two separate apertures 276a, 276 b. Each of the apertures 276 a,b span a portion of the side wall254, the top wall 252 and the center portion 270. Alternatively, theapertures 276 a, 276 b span only a portion of the side wall 254 and thetop wall 252.

As shown in FIG. 5, the aperture 276 is adapted to permit the passage orflow of the flowable contents held by the container through the opening228 when the aperture is generally positioned about the opening 228.Described in another manner, when the aperture 276 is aligned with theopening 228, the flowable contents can pass through the opening 228.Therefore, the aperture 276 should have a minimum configurationsufficient to permit the passage of the flowable contents through theaperture 228.

The cover 212 and the overlay 250 each have a generally thin-wallconstruction. However, the wall thickness of the cover 212 and theoverlay 250 can vary depending upon the design parameters, including thestructural integrity of the lid 210.

Referring to FIGS. 5 and 8, the overlay 250 and the cover 212 arecooperatively dimensioned such that the overlay 250 can be positioned onthe cover 212 to define an “assembled position.” In the assembledposition, the overlay 250 is rotatably supported by the engagement ofits mounting portion 260 and the mounting portion 222 of the cover 212.Specifically, a lower surface of the mounting portion 260 engages anupper surface of the mounting portion 222. Accordingly, the mountingportion 260 and the mounting portion 222 are cooperatively dimensionedsuch that the overlay 250 can be rotated with respect to the cover 212,where the cover 212 is generally fixed to the container.

In addition, the overlay 250 can be rotatably supported by theengagement of its center portion 270 and the center portion 236 of thecover 212. Specifically, a lower surface of the center portion 270engages an upper surface of the center portion 236. Accordingly, thecenter portion 270 is cooperatively dimensioned with the center portion236 of the cover 212. Alternatively, the lid 210 can be configured tohave a clearance between the center portions 236, 270 such that thecenter portions 236, 270 are not in engagement. In this configuration,the overlay 250 rotatably engages the cover 212 by the engagement of themounting portions 222, 260.

Alternatively, the overlay 250 can be rotatably supported by theengagement of its top wall 252 with the top wall 214 of the cover 212.Accordingly, the top wall 252 is cooperatively dimensioned with the topwall 214 of the cover 212. In another alternative, the overlay 250 canbe rotatably supported by the engagement of its side wall 254 with theside wall 216 of the cover 212. Accordingly, the side wall 254 iscooperatively dimensioned with the side wall 216 of the cover 212.

In the assembled position, the overlay 250 is movable between a firstposition P1 and a second position P2. In the first position P1, shown inFIG. 8, the projection 264 is received by the drink opening 228 suchthat the opening 228 is sealed wherein the lid 210 is closed. When theopening 228 is sealed, the edge 229 of the opening 228 is in frictionalengagement with the projection 264. A bottom portion (not shown) of theprojection 264 can extend past the edge 229 of the drink opening 228.This seal prevents the flow of the flowable substance in the containerthrough the opening 228, enabling the container and lid 210 to be movedwithout risking spillage. Also, in the first position P1, the aperture276 is misaligned or offset from the opening 228. Alternatively, theprojection 264 and the opening 228 are in a snap fit engagement whereineach have sufficient structure to enable the snap fit engagement. Othercooperating sealing structures can also be utilized.

In the second position P2, shown in FIG. 5, a user rotates the overlay250 wherein the aperture 276 is aligned with the drink opening 228 toform a passageway between the overlay 250 and the cover 212. In thesecond position P2, the lid 210 is open. The passageway permits thepassage or flow of the flowable substance held by the container throughthe lid 210. When the lid 210 is in the second position P2, at least aportion of the aperture 276 is aligned with at least a portion of theedge 229 of the drink opening 228. Also, in the second position P2, atleast a portion of the recessed portion 240 of the cover 212 is alignedwith the aperture 276. In addition, in the second position P2, theprojection 264 is misaligned or offset from the opening 228. When theaperture 276 is partially aligned with the drink opening 228, thepassageway remains but its dimensions are reduced.

When the overlay 250 is moved between the first position P1 and thesecond position P2, the mounting portion 260 of the overlay 250 remainsin rotatable engagement with at the mounting portion 222 of the cover212. Accordingly, the mounting portions 222, 260 provide support to theoverlay 250 such that the overlay 250 remains in the assembled positionduring movement between the first and second positions, P1, P2.

When the overlay 250 is moved between the first position P1 and thesecond position P2, the center portion 270 of the overlay 250 remains inrotatable engagement with the center portion 236 of the cover 212.Accordingly, the center portions 236, 270 provide an additional amountof support to the overlay 250 such that the overlay 250 remains in theassembled position during movement between the first and secondpositions, P1, P2.

A user can move the overlay 250 between the first position P1 and thesecond position P2 by grasping and manipulating a portion of the overlay250, for example, the side wall 254, the top wall 252 or the mountingportion 260. Alternatively, when so configured, the user can move theoverlay 250 between the first and second positions P1, P2 by engagingthe gripping element 274.

The overlay 250 can be rotated or moved a varying amount depending uponthe numerous design parameters of the lid 210, including but not limitedto the configuration and dimensions of the side wall 254, the mountingportion 260, the projection 264 and the aperture 276. Thus, the overlay250 can assume a number of positions with respect to the cover 212. Thelid 210 is adapted to permit a user to move the overlay 250 between thefirst and second positions P1, P2 with only one hand. This means that auser can hold the container and manipulate the overlay 250 with the samehand. This increases the flexibility and the commercial value of the lid210. As shown in FIGS. 5, 7 and 8, the overlay 250 has two separateapertures 276 which permit the overlay 250 to be rotated in either aclockwise or counter-clockwise direction to move the overlay 250 betweenthe first position P1 and the second position P2. This feature furtherincreases the flexibility and the commercial value of the lid 210.

The lid 210 is adapted to be used without the overlay 250. This meansthat the cover 212 is connected to a container but the overlay 250 isomitted. In this configuration, there is no structure to seal theopening 228 in the cover 212 and as a result, the flowable substanceheld by the container can pass through the lid 210. In thisconfiguration, the recessed portion 240 remains positioned on both thetop wall 214 and the side wall 216. However, the drink opening 228 canbe positioned in either the top wall 214 or the side wall 216.

Although shown as having a generally circular shape, the lid 210,including the mounting portions 222, 260, can have numerousconfigurations. For example, the lid 210 could have a rectangular,square, or oval shape. To ensure a leak-proof seal with the container,the shape of the mounting portion 222, 260 should match the shape of theupper edge of the container so a cooperative sealing engagement can beachieved.

Alternatively, the mounting portions 222, 260 could have a shape similarto the upper edge of the container, yet dissimilar from the shape of theside walls 216, 254 and the top walls 214, 252. For example, themounting portions 222, 260 could have an annular shape consistent withthe container shape and the side walls 216, 254 and/or the top walls214, 252 could have a non-annular shape.

Unlike prior art designs, the dimensions and the configuration of theopening 228 are not affected by the engagement and disengagement of theprojection 264 as the overlay 250 is moved between the first and secondpositions P1, P2. This attribute allows a user to repeatedly move theoverlay 250 between the first position P1 and the second position P2.Accordingly, the structural integrity and the durability of the lid 210are increased.

The lid 210 can be formed by a variety of manufacturing processes, suchas injection molding or a thermoforming operation, preferably vacuumforming and/or pressure forming. The cover 212 is preferably formed fromplastic, however, other lightweight materials can be used to form thecover 212. After the manufacturing process has been completed, the drinkopening 228 may be formed in the cover 212 with a punch and die. Theaperture 276 could also be formed with a punch and die.

Preferably, the overlay 250 is formed from the same material used toform the cover 212. However, the overlay 250 can be formed from otherlightweight materials.

The cover 212 can have at least one cover drain hole (not shown),preferably positioned in the center portion 236 near a lowermost portionof the center portion 236. When excess flowable contents, e.g., liquid,accumulate on the cover 212, the drain hole ensures the drainage of suchcontents into the container.

The overlay 250 can have an overlay drain hole (not shown), that iscooperatively dimensioned with the cover drain hole described above. Theoverlay drain hole is cooperatively positioned with the cover drain holesuch that when the overlay 250 is rotated to the first position P1, thecover drain hole and the overlay drain hole align to form a passagewaythat ensures the drainage of accumulated container contents.Alternatively, the overlay drain hole is cooperatively positioned withthe cover drain hole such that when the overlay 250 is rotated to thesecond position P2, the cover drain hole and the overlay drain holealign to form the passageway.

The cover 212 can have at least one cover vent hole (not shown),preferably in the center portion 236 or the side wall 216.Alternatively, the cover vent hole is positioned in a portion of the topwall 214 or a portion of the side wall 216. The cover vent hole isadapted to ensure the continuous flow of the container contents thoughthe opening 228 while venting the container. Preferably, the cover venthole is positioned such that the venting of the container occurs whilethe lid 210 is in the second position P2.

The overlay 250 can have an overlay vent hole (not shown), that iscooperatively dimensioned with the cover vent hole described above. Theoverlay vent hole is cooperatively positioned with the cover vent holesuch that when the overlay 250 is rotated to the second position P2, thecover vent hole and the overlay vent hole align to form a passagewaythat ensures the venting of the container.

The drain holes and the vent holes described above can be formed with apunch and die after the lid 210 manufacturing process has beencompleted. Alternatively, a pointed tool may be used to form the drainholes and the vent holes.

In another preferred embodiment (not shown), the lid has at least onepin on either the overlay or the cover. In addition, the lid has atleast one socket on the other of the overlay or the cover. The pin andthe socket are cooperatively dimensioned such that when the pin isreceived by the socket, the overlay is in rotational engagement with thecover. Because the overlay and the cover are in rotational engagement,the lid can be rotated between the first and second positions P1, P2.The pin and socket are adapted to support the overlay when the lid isrotated between the first and second positions P1, P2.

The cover has a center portion that can be recessed. The overlay is adiscontinuous structure that is adapted to be positioned about thecover. The overlay has at least one aperture that is alignable with anopening in the cover. Preferably, the pin depends from a lower surfaceof the overlay, and the socket depends from an upper surface of thecover. In this configuration, the socket is positioned in the centerportion of the cover.

The overlay can include an annular mounting portion that engages amounting portion of the cover. The overlay mounting portion supports theoverlay during movement between the first and second positions.Alternatively, the overlay includes a mounting portion but it issegmented, meaning that it is not annular.

In another alternative, the annular mounting portion is omitted from theoverlay. In this configuration, the pin and socket primarily support theoverlay when the lid is rotated between the first and second positionsP1, P2.

FIGS. 9 and 10 disclose an alternate embodiment of a lid of the presentinvention, generally designated with the reference numeral 310. The lid310 generally includes a cover 312 and the movable or rotatable elementor disk 50, and the similar elements thereof retain their referencenumerals. The lid 310 is shown having a tab 323 extending from a portionof the cover 312. The tab 323 is adapted to permit a user to easilyposition and/or remove the lid 310 from a container 325. The tab 323extends radially outward from the mounting portion 322. Described in adifferent manner, the tab 323 extends radially from the peripheral edge360 of the skirt 326. However, the tab 323 can extend from a differentportion of the cover 312, including the side wall 16 or the flange 324.Although a single tab 323 is shown, the lid 310 can have a plurality oftabs 323 wherein the tabs 323 are spaced about the mounting portion 322.The tab 323 has a curved peripheral edge 327 that causes the tab 323 tohave a curvilinear configuration. Alternatively, the tab 323 has anangular or linear configuration. As shown in FIG. 11, the thickness ofthe tab 323 generally corresponds to the thickness of the mountingportion 322. However, the thickness of the tab 323 can be eitherincreased or decreased as necessary.

An alternate tab 423 extending from the mounting portion 322 is shown inFIG. 12. The tab 423 has a curvilinear configuration with a firstsegment 429, a second segment 431, and a third segment 433. The firstsegment 429 extends radially outward from an edge 360 of the skirt 326.The second segment 431 is angled or sloped upward from the first segment429 to the third segment 433 whereby the tab 423 has a “stepped”configuration. The third segment 433 has a rounded edge 427 which causesthe tab 423 to have a curvilinear configuration. Alternatively, thethird segment 433 has a squared end or terminus. When viewed from above,a channel 435 is defined by the skirt 326, the first segment 429, andthe second segment 431. The first segment 429 defines a first plane, thesecond segment 431 defines a second plane, and the third segment 433defines a third plane. Due to the angled second segment 431, the firstplane and the third plane are misaligned. Described in a differentmanner, the first plane is not in planar alignment with the third plane.Further, neither the first plane nor the third plane are in planaralignment with a plane defined by the flange 324. In another alternative(not shown), the tab has a second segment that is angled or slopeddownward from the first segment towards the third segment causing thetab to have a stepped configuration in a downward direction. With thisalternate design, the third segment is positioned lower than the skirtof the mounting portion.

As described above, the lid 310, or portions thereof can be formed by avariety of manufacturing processes, such as injection molding or athermoforming operation, preferably vacuum forming and/or pressureforming. However, the primary components of the lid, the cover 312 andthe rotatable element 50, can be formed from distinct processes. Forexample, the cover 312 can be thermoformed while the rotatable element50 can be injection molded. Furthermore, the cover 312 and/or theelement 50 can be co-injection molded, meaning that multiple polymerscan be used to form the element 50. For example, the rotatable element50 can be formed from a thermoplastic polymer and a thermoset polymer.In addition, an additive such as a filler, plasticiser, stabilizer, orcolorant can be utilized to form the cover 312 and/or element 350.

Preferably, the tab 323 is integrally formed with the cover 312.Preferably, the thickness of the tab 323 corresponds with the cover 312,however, it can differ based upon design parameters of the lid 310. Aconventional cutting tool is used to trim excess material from the lid310 to form the tab 323. The precise configuration and/or thickness ofthe tab 323 can be revised by the changing the operating parameters ofthe cutting tool.

As also mentioned above, the tab 323 is adapted for a user to easilyposition and/or remove the lid 310 from the container 325. When the lids310 are stacked in a vertical arrangement at a retail distributionpoint, an employee can grasp the tab 323 to quickly separate theuppermost lid 310 from others within the stack. The tab 323 furthers theassembly of the cover 312 and the rotatable element 50. During the stepof assembling the cover 312 and the rotatable element 50, the tab 323helps to fix the position of the cover 312 such that the rotatableelement 50 can be properly positioned within the interior region of thecover 312. The tab 323 enhances the alignment between the cover 312 andthe element 50 to effectuate the assembly of the lid 310. Referring toFIG. 10, the tab 323 of the lid 310 is shown positioned between a pairof guides or pegs G, which typically extend from a piece of equipment ortooling. Alternatively, the tab 323 is positioned against a single guideG. The interaction between the guides G and the tab 323 secures the lid310 in a pre-assembly position wherein the cover 312 is separated fromthe rotatable element 50. In the pre-assembly position, the preciselocation of the slot 30 is fixed to facilitate reception of the actuator54. Described in a different manner, the angular orientation of thecover 312, including the slot 30 is fixed. While the tab 323 ispositioned between the guides G, the rotatable element 50 is movedtowards the interior region of the cover 312. To reach an assembledposition, the rotatable element 50 is positioned within the interiorregion of the cover 312 whereby the actuator 54 is received by the slot30. In addition, the rotatable element 50 is positioned such that itrotatably engages the support members 102. Thus, the tab 323 helps toensure the proper assembly and formation of the lid 310. In addition toproviding positioning benefits during assembly of the lid 310, the tab323 provides positioning benefits during the use of the lid 310.Specifically, the tab 323 provides tactile feedback for a user todetermine the position of the drink opening 28 with respect to theposition of the tab 323. This aspect is beneficial in low lightconditions.

As shown in FIG. 1, the cover 12 has a drink opening 28 that is adaptedto receive the projection 52 of the rotatable element 50 in the firstposition P1. The drink opening 28 is shown as being positioned in thetop wall 14 of the cover 12. However, a spout can extend upward in agenerally vertical manner from the top wall 14 and include a drinkopening. In this manner, the drink opening is positioned above the topwall 14 due to the spout. In the first position P1, the flowablecontents of the container flow through the aperture 78 of the element 50and the spout. The spout can extend upwardly from the top wall 14 or acombination of the top wall 14 and the central region 36. Preferably,the spout is integrally formed with the cover 12. The dimensions of thespout, including the height and the width, vary with the designparameters of the lid 10. Preferably, the spout is cooperativelydimensioned with the projection 52 such that a base region of the spoutreceives the projection 52 to generally seal the opening 28 of the lid10 in the second position P2.

Referring to FIG. 3 and as mentioned above, the cover 12 has a pluralityof support members 34 and support ledges 102, where the support ledges102 extend into the interior region of the cover 12 from the side wall16. As shown in FIG. 13, a cover 412 has a support ledge 102B that ispositioned within the recessed portion 40 of the side wall 16 and nearthe drink opening 28. Alternatively, the recessed portion 40 is omittedand the support ledge 102B is positioned near the drink opening 28. Inyet another alternative, a pair of support ledges 102B can extend inwardfrom the side wall 16 and be positioned about the drink opening 28. Asfully explained above, the rotatable element 50 is rotatably supportedby the ledges 102 such that the element 50 is moveable between the firstand second positions P1, P2. As shown in FIG. 13, the support ledge 102Bhas a reduced length compared to the other support ledges 102. However,the dimensions including the length of the support ledges 102, 102B canvary with the design parameters of the cover 12. The positioning of thesupport ledge 102B near the drink opening 28 enhances the operation ofthe rotatable element 50. In the first or closed position P1, thesupport ledge 102B provides further support to the element 50 such thatthe projection 52 is properly received by the drink opening 28. In thesecond or open position P2, the support ledge 102B provides furthersupport to the element 50 such that the aperture 78 remains properlyaligned with the drink opening 28. Furthermore, in either position P1,P2, the interaction between the support ledge 102B and the rotatableelement 50 minimizes the chance for seepage past the element 50 in theregion about the drink opening 28. Although the cover 412 is shown asnot having the tab 323 of FIGS. 9-11, it is understood that the cover412 can have a tab and that such structure will not interfere with theoperation of the lid 412.

As shown in FIG. 13, the support ledges 102, 102B extend radially inwardfrom the inner surface 100 of the side wall 16 of the cover 412.Alternatively, the cover 412 has a support channel in the side wall 16wherein the channel is adapted to rotatably support the element 50. Inthis manner, the support channel is recessed into the side wall 16 suchthat it does not extend beyond the inner surface 100. The supportchannel can be positioned along the entire circumference of the sidewall 16, or an extent of the circumference. The support channel can becontinuous or interrupted, meaning spaced along the circumference of theside wall 16. Preferably, the element 50 has a rib or rail that isreceived by the support channel to rotatably support the element 50. Toensure proper rotation of the rotatable element 50, the rib and thesupport channel are cooperatively dimensioned. The rib can extend from anumber of locations of the element 50, including the top wall 56, theside wall 59, or the lower edge 51. Like the support channel, the ribcan be continuous or interrupted. For larger containers, the size of thecover 12 can be increased such that cover 12 has a plurality of supportchannels and the rotatable element 50 has a corresponding number ofcooperating ribs. Preferably, the support channel in the side wall 16 isdimensioned to receive only the rib of the element 50. Alternatively,the height of the support channel is increased such that a greaterextent of the element 50 is rotatably received. This means at least theouter edge 51 and the side wall 59 of the element 50 are received by thelarger support channel. In another alternative, the support channel andrib configuration is reversed such that the rotatable element 50 has arecessed channel that receives a rib of the cover 12.

As explained above, the rotatable element 50 is moveably supported bysupport ledges 102 located in the side wall 16. Alternatively, therotatable element 50 is rotatably supported by other portions of thecover 12 such as the top wall 14 and/or the central portion 36 of thecover 12. Thus, the top wall 14 could have at least one structureadapted to rotatably support the element 50. For example, a supportledge 102 can depend from the top wall 14 and rotatably support theelement 50. In this configuration, the support ledge 102 depends fromthe top wall 14 at a position radially inward of the peripheral edge ofthe top wall 14. This support ledge 102 has a horizontal component thatengages and rotatably supports the element 50, which can be aring-shaped structure. As another example, a support ledge 102 candepend from the central portion 36 and rotatably support the element 50.As yet another example, a support ledge 102 can extend from the pointwhere the top wall 14 and the side wall 16 converge. In is furtherunderstood that the element 50 could be rotatably supported on a topsurface of the cover 12.

Referring to FIG. 4, the rotatable element or disk 50 has an aperture 78that is aligned with the drink opening 28 in the second or open positionP2. Alternatively and as shown in FIG. 14, the aperture 78 is omittedand the element 450 has at least one structure configured to define apassageway for the flow of the container contents. In a preferredembodiment, the element 450 has a notch 478 that defines a channel orpassageway 479. The dimensions of the passageway 479 are determined bythe width and length of the notch 478. The notch 478 extends radiallyinward from the outer edge 51 of the element 450. The notch 478terminates prior to the top wall 56 of the element 450. However, thenotch 478 can extend into the top wall 56 and/or into the inner shoulder60 of the element 450. The notch 478 is positioned adjacent the recessedportion 84 of the element 450. In the first position P1, the notch 478is misaligned with the drink opening 28 causing misalignment between thepassageway 479 and the opening 28. In the second position P2, the notch478 is generally aligned with the drink opening 28 causing thepassageway 479 to be aligned with the opening 28. As a result, thepassageway 479 permits the passage of the flowable substance held by thecontainer through the lid 10. In yet another alternative, the element450 has an upwardly directed or raised segment that defines a channel orpassageway. To prevent binding of the rotatable element during itsmovement between the first and second positions P1, P2, the height ofthe raised segment corresponds to the height of the projection 52.

As discussed above and as shown in FIG. 14, the center or centralportion 462 of the rotatable element 450 has an opening 463. As a resultof the opening 463, the element 450 has a ring-shaped configuration. Theopening 463 is adapted to permit the drainage of the liquid contents ofthe container pass between the element 450 and the cover 12. Althoughthe diameter of the opening 463 is shown as roughly corresponding to thediameter of the wells 90, the size of the opening 463 can vary with thedesign parameters of the rotatable element 450. As a result, thedimensions of the ring-shaped element 450 will vary. For example, thediameter of the opening 463 is increased and the width of the centerportion 462 corresponds to the width of the top wall 56 of the rotatableelement 450.

In another embodiment, the rotatable element 50 has a band extendingradially outward from the peripheral or outer edge 51 proximate theprojection 52. The band is adapted to increase the sealing of the drinkopening 28 by the projection when the lid 10 is in the closed or firstposition P1. Preferably, the band has a rectangular configuration andextends outward from the recessed portion 84 of the element 50. When thelid 10 is in the closed position P1, the band is positioned beneath thedrink opening 28 and against the inner surface 100 of the cover 12. Inthis manner, the band helps to further seal the drink opening 28 in theclosed position P1. The rotatable element 50 could also have aprojection 52 with pliable characteristics to assist in sealing thedrink opening 28. This type of projection 52 can be formed, for example,using a two-shot injection molding process.

In another embodiment, the rotatable element 50 has a recessed portion84 with a vertical side wall 59. When the element 50 is viewed from theside, the vertical side wall 59 forms a shoulder or ledge (not shown)near the peripheral edge 51 of the element 50. The shoulder has avertical wall component that originates at the peripheral edge andterminates near the edge 80 of the aperture 78. The shoulder extends anextent of the recessed portion 84. Preferably, the shoulder extendsalong the projection 52 and the aperture 78. The vertical side wall 59is adapted to aid the interaction between the recessed portion 84 andthe recess 40 of the cover 12.

FIGS. 15 and 16 disclose an alternate embodiment of a lid of the presentinvention generally designated with the reference numeral 510. The lid510 generally has a cover 512 and the rotatable element 550, and thesimilar elements thereof retain their reference numerals. The lid 510has a slot 530 with increased dimensions. Specifically, the arc lengthof the slot 530 is increased. In the first or closed position P1 shownin FIG. 15, the actuator 54 is positioned between a first slot portion530 a and a second slot portion 530 b. Thus, two distinct slot portions530 a, b flank the actuator 54 in the first position P1. In the firstposition P1, the actuator 54 is positioned at the general midpoint ofthe slot 530. The rotatable element 550 has a first aperture 78 and asecond aperture 578, wherein the apertures 78, 578 are positioned aboutthe projection 52. Preferably, the second aperture 578 is positioned inthe recessed portion 84 of the element 550. Like the first aperture 78,the second aperture 578 has a peripheral edge 580 that defines the shapeof the aperture 578. When the second aperture 578 is aligned with thedrink opening 28, a passageway is formed between the disk 50 and thecover 512 permitting the passage or flow of the flowable substance heldby the container through the lid 510. To move the lid 510 from the firstposition P1 to the open or second position P2, a user actuates theactuator 54 in either a clockwise or counter-clockwise direction suchthat either the first aperture 78 or the second aperture 578 is alignedwith the drink opening 28. Therefore, the lid 510 is capable of movementin one of two distinct directions from the first position P1 to thesecond position P2, which increases the utility of the lid 510.Alternatively, the lid 510 has a pair of projections 52 positioned aboutthe first aperture 78. In this configuration, to move the lid 510 fromthe second position P2 to the closed or first position P1, a useractuates the actuator 54 in either a clockwise or counter-clockwisedirection such that either the first projection 52 or the secondprojection 52 is received by the drink opening 28.

Although the rotatable element 50 is shown in FIG. 4 as having a diskconfiguration, the element 50 can have a variety of configurations. Forexample, the rotatable element 50 can have a ring-shaped configuration.Also, at least one spoke or rib can be added to the ring-shaped element50 to increase its structural integrity. The spoke(s) can have arecessed central portion that corresponds with the recessedconfiguration of the central region 36 of the cover 12. Alternatively,the rotatable element 50 can have a hour-glass shaped configurationwhere the portions not having either the post 54 or the recessed portion84 are removed. This configuration reduces the quantity of material usedto fabricate the rotatable element 50.

Again referring to FIG. 4, the rotatable element 50 has an actuator 54defined by a post that extends generally upward from a top wall 56 ofelement 50. Alternatively, the post 54 depends downward from the topwall 56 to define a well. The well is cooperatively dimensioned with theslot 30 of the cover 12 such that a user can actuate the lid 10 betweenthe first position P1 and the second position P2. For example, a usercan insert a finger into the slot 30 and the well formed by thedepending post 54 to actuate the element 50 between the first and secondpositions P1, P2. Thus, the well is adapted to receive a user's fingerto actuate the rotatable element 50. In another alternative, theactuator 54 is defined by a plurality of protrusions such that a usercan engage the protrusions to actuate the rotatable element 50 betweenthe first and second positions P1, P2.

FIGS. 17 and 18 disclose an alternate embodiment of a lid of the presentinvention generally designated with the reference numeral 610. As showntherein, the support members 34 and the resulting support ledges 102 areomitted from the side wall 616 of the cover 612. Also, the actuator orpost 654 of the rotatable element 650 has a flange 671 that is adaptedto slidingly engage the top wall 14 of the cover 612. As explainedabove, in an assembled position, the post 654 extends through the slot30 in the cover 612 wherein the flange 671 slidingly engages a portionof the top wall 14 of the cover 12. This means that a lower surface ofthe flange 671 slidingly engages the upper surface 14 a of the top wall14. The interaction between the flange 671 and the top wall 14 providesmoveable support for the element 650 such that the element 650 isrotatable between the first position P1 and the second position P2.Thus, the flange 671 provides means for supporting the element 650within the internal cavity 38 of the cover 612 whereby the element 650is rotatable between the first and second positions P1, P2.

As shown in FIGS. 17 and 18, the flange 671 is positioned about the endwalls 674 and the side walls 674, but below the top wall 676 of the post654. Also, the flange 671 extends from the periphery of the post 654such that the post 654 has a “T-shaped” configuration. Preferably, theflange 671 is integrally formed with the post 654 and is flexible. As aresult, when the post 654 is inserted into the slot 30 during theassembly process, the flange 671 flexes as it passes through the slot 30and then returns to its original configuration (meaning un-flexed) whenit clears the slot 30. The flange 671 defines a plane that is in planaralignment with a plane defined by the top wall 14 of the cover 612.Alternatively, the flange 671 is angled, peaked, or sloped. The flange671 has a length and a width, wherein each is greater than a length andwidth of the post 654. Preferably, the width of the flange 671corresponds with the width of the top wall 14 of the cover 612. One ofordinary skill recognizes that the dimensions of the flange 671 can notbe so great as to preclude the passage of the flange 671 through theslot 30.

The lid 610 is shown as having the flange 671 and no support members 34.However, the lid 610 can have a combination of these structures. Forexample, the lid 610 could include the flange 671 and at least onesupport member 34 and the resulting support ledge 100. In thisconfiguration, the element 650 is rotatably supported by the interactionbetween the flange 671 and the top wall 14 and by the interactionbetween the peripheral edge 51 of the element and the support ledge 100.As another example, the lid 610 could have two or more posts 654 and acorresponding number of slots 30, wherein each post 654 has a flange 671that slidably engages the top wall 14 of the cover 612 near eachrespective slot 30. In this manner, the element 650 is rotatablysupported by the interaction between multiple flanges 671 and the topwall 14.

FIGS. 19-22 disclose an alternate embodiment of a lid of the presentinvention generally designated with the reference numeral 710. The lid710 generally has a cover 712 and the rotatable element 750, and thesimilar elements thereof retain their reference numerals. The cover 712has a side wall 716 with a vertical channel or rib 717. The verticalchannel 717 is internal to the cover 712, however, the channel 717protrudes from the outer surface 716 a of the side wall 716. This meansthat the side wall 716 is raised at the channel 717. The channel 717extends between the lower edge 20 of the side wall 716 and theperipheral edge 18 of the top wall 714. This means that the channel 717is positioned between the mounting portion 22 and the top wall 714. Thechannel 717 is adapted to provide a first passageway for the flow of theflowable contents through the lid 710. In this manner, the channel 717provides a generally vertical passageway for the content to flow to theopening 28 of the lid 710.

Referring to FIG. 22, the rotatable element 750 has a first projection752 and a second projection 753. The projections 752, 753 are spaced adistance apart but remain within the recessed portion 784 of the element750. Since the portion 784 is recessed or depressed with respect to thetop wall 756 of the element 750, the element 750 has transition walls785 between the top wall 756 and the recessed portion 784. Furthermore,the recessed portion 784 defines a plane that is below a plane definedby the top wall 756. Unlike recessed portions discussed above, therecessed portion 784 has increased dimensions such that the recessedportion 784 extends to the peripheral edge 751 of the element 750.Described in a different manner, the recessed portion 784 has anextended portion 784 a that is coincident with the peripheral edge 751.As a result, an extent of the outer shoulder 758 and the side wall 759proximate the extended portion 784 are omitted. Due to the configurationof the recessed portion 784, the aperture 78 is omitted. The recessedportion 784 is adapted to provide a second passageway for the flow ofthe flowable contents through the lid 710. The rotatable element 750 hasan opening 763 and a plurality of wells 790 positioned radially outwardof the opening 763. The recessed portion 784 is shown as spanning a pairof wells 790, however, the dimensions of the portion 784 can vary withthe design parameters of the lid 710.

The lid 710 is movable between a closed or first position P1 and an openor second position P2. In the first position P1 shown in FIGS. 19 and21A, the first projection 752 is received by the drink opening 28 of thecover 712. The second projection 753 is positioned beneath the top wall714 but preferably beyond the lip recess 40 of the cover 712. Also, thechannel 717 is positioned between the first and second projection 752,753. Furthermore, the post 54 of the rotatable element 750 extendsthrough the slot 30 of the cover 712. Although the vertical channel 717creates a fluid passageway, the first projection 752 obstructs fluidflow through the drink opening 28 of the cover 712.

Consistent with that explained above, the post 54 is actuated to movethe lid 710 between the first and second positions P1, P2. In the openor second position P2 shown in FIG. 21B, both the first projection 752and the second projection 753 are misaligned with the drink opening 28.Described in a different manner, the first and second projections 752,753 are positioned about the opening 28. Referring to FIG. 21B, thefirst projection 752 is shown as being positioned beyond the opening 28,while the second projection 753 is not shown due to the section lineused to section FIG. 19. In the second position P2, the recessed portion784 of the element 750 is in fluid communication with the channel 717.Specifically, the extended portion 784 a of the recessed portion 784 isin fluid communication with the channel 717. In the second position P2,the second projection 753 is positioned between the drink opening 28 andthe channel 717. In the second position P2, the interaction between thecover 712 and the projections 752, 753 exerts a downwardly directedforce on the element 750 which deflects the element 750. This deflectionof the element 750 creates a clearance C between the inner surface ofthe cover 712 and the rotatable element 750. Specifically, theinteraction between the first projection 752 and/or second projection753 and an inner surface of the top wall 40 c of the recessed portion 40causes the element 740 to deflect or flex which results in the clearanceC near the drink opening 28 of the cover 712. The clearance C is afunction of the deflection of the rotatable element 750. Preferably, theregion of deflection of the element 750 is the recessed portion 784. Thetop wall 40 c of the recessed portion is positioned below the top wall714 of the cover 712 which is evidenced by the notch or step between thetop wall 40 c and the top wall 714. The clearance is further defined bythe extended portion 784 a of the recessed portion 784 of the rotatableelement 750. The clearance C completes the fluid passageway that allowsthe container contents to flow through the drink opening 28.Accordingly, the fluid passageway is formed by the vertical channel 717and the clearance C between the rotatable element 750 and top wall 40 cabout the drink opening 28. The clearance C is maintained while therotatable element 750 is rotatably supported by the support members 102of the cover 712. The top walls 714, 40 c are dimensioned such that thefirst projection 752 and/or the second projection 753 can slidinglyengage the inner surface thereof to permit movement between the firstand second positions P1, P2.

FIGS. 23-28 disclose another embodiment of the reclosable lid of thepresent invention, generally designated with the reference numeral 810.Like the previous embodiments, the lid 810 is adapted to be attached toa container 825. The container 825 has a central opening defining avolume that can be used to hold or contain a flowable substance, forexample a liquid. The container 825 and the lid 810 can be of either thedisposable or extended use variety. FIGS. 23 and 24 show the lid 810 ina closed position P1 wherein the lid 810 is sealed such that theflowable substance cannot flow through the lid 810. FIG. 28 shows thelid 810 in an open position P2, wherein a flowable substance may flowfrom the container 825 and through the lid 810. The lid 810 generallycomprises a cover 812 and a moveable or rotatable element 850.

The cover 812 is adapted to be attached to the container 825 that holdsa flowable substance. The cover 812 is adapted to span the opening inthe upper portion of the container 825 that is generally defined by anupper rim or edge 827 of the container 825. For illustrative purposes,the container 825 could be a coffee cup having an opening defined by therim of the cup. The cover 812, as illustrated in FIGS. 23-25, generallyhas a top wall 814, a side wall 816, and a mounting portion 822 adaptedto be attached to the container 825.

The top wall 814 is generally annular, although other configurations arepossible. The side wall 816 depends from a peripheral edge 818 of thetop wall 814. Although the top wall 814 is shown as having a generallylevel upper surface 814 a, the upper surface 814 a can be curved orangled. The side wall 816 has a side wall surface 816 a and a lower edge820. The side wall surface 816 a can be curved or generally flat. Theoverall shape of the cover 812 is generally frustoconical, however, thecover 812 can have a number of other configurations.

A mounting portion 822 depends from the lower edge 820 of the side wall816, and can be considered as part of the side wall 816. The mountingportion 822 includes a generally annular flange 824 and a generallyannular skirt 826. The mounting portion 822 is adapted for connectingthe lid 810 to the container 825 in a manner that seals the lid on thecontainer 825. Thus, the mounting portion 822 prevents leakage of thecontainer 825 contents between the lid 810 and the container 825 whenthe lid 810 is positioned on the container 825. In a preferredembodiment, the mounting portion 822 is integral with the side wall 816.

A drink opening 828 is located preferably in the top wall 814.Alternatively, the opening 828 is located in the side wall 816. Theopening 828 is adapted to permit the passage or flow of the flowablecontents held by the container 825 through the cover 810. The opening828 has an edge 829 that defines the shape of the opening 828. Althoughshown in FIGS. 23-25 as having an obround shape, the opening 828 canhave a variety of shapes, including but not limited to circular, square,or rectangular.

A slot or channel 830 is located preferably in the top wall 814.Alternatively, the slot 830 may be located in the side wall 830. Theslot 830 permits access to the actuator 854 used for rotating themoveable element 850 as described in greater detail below. The slot 830has an edge 832 that defines the shape of the slot 830. Although shownin FIGS. 23-25 as having an obround shape, the slot 830 can have avariety of shapes, including but not limited to circular, square, orrectangular. Because the slot 830 must provide access to the actuator854, the shape and size of the slot 830 will be related to the form andsize of the actuator 854. As previously described, in an alternateembodiment, the moveable element 850 can have two apertures. While mostfeatures of the cover 810 need not be changed to adapt to adouble-aperture element, the slot 830 may need to be enlarged toaccommodate the larger range of motion required to move betweenadditional positions.

As further shown in FIGS. 23, 25 and 27, the cover 810 has a supportmember 837, which preferably depends from a central portion 836 of thetop wall 814. In a most preferred embodiment, the support member 837depends from a center of the top wall 814. The support member 837 isadapted such that the rotatable element 850 may be rotatably mounted onthe support member 837. The support member 837 is generally acylindrical protrusion in the underside of the top wall 814, and has aninner side wall 837 a and an outer side wall 837 b. Alternatively, thesupport member 837 may be embodied in one of many other shapes andforms. For example, the support member 837 may contain or comprise a lipor cusp (not shown) for securing the disk. Furthermore, although in thepreferred embodiment, the support member 837 is located substantially inthe center of the top wall 814, it need not be located in the center,nor even in the top wall 814. Additionally, the support member 837 neednot depend from the top wall 814, and may comprise any form on which theelement 850 may be rotatably mounted, for example a depression on theunderside of the top wall 814 (which may form a projection from theupper side of the top wall) or an aperture through the top wall 814.Preferably, the support member 837 is integral with the top wall 814,but a separable support member would function suitably. In addition, thesupport member 837 may comprise a separate rivet member. The supportmember 837 could also comprise a generally arrowhead-shaped member thatcooperates with an opening in the moveable element 850. The supportmember 837 could also form part of a ball and socket arrangement withthe moveable element 850 to rotatably support the element 850. It isfurther understood that in a preferred embodiment, the element 850 isrotatably supported on an underside of the cover 812. It is appreciated,however, that the element 850 could be supported on a top surface of thecover 812 to provide the reclosable lid of the present invention.

As shown in FIG. 23, the top wall 814 has a center portion 836 which ispreferably recessed such that the center portion 836 has a curvilinearconfiguration when viewed in cross-section. The degree of recess orcurvature of the center portion 836 can vary with the design parametersof the lid. Alternatively, the entire top wall 814 is in planaralignment. In this configuration, the center portion 836 is notrecessed.

Referring to FIGS. 23 and 24, the side wall 816 has a recessed portion840, which is adapted to receive a lip of a person drinking from thecontainer. An edge 842 of the recessed portion 840 defines theconfiguration of the portion. The recessed portion 840 is positionedradially inward from the side wall surface 816 a. Although the recessedportion 840 is shown positioned on both the top wall 814 and the sidewall 816, the recessed portion 840 can be limited to either the top wall814 or the side wall 816. The shape and configuration of the recessedportion 840 can be varied to conform to numerous design parameters.Similarly, the degree of recess of the portion 840 can vary. Forexample, as shown in FIG. 1, the recessed portion 840 is deeper at abase portion and shallower at an end proximate the drink opening 828.Preferably, the recessed portion 840 is positioned about the drinkopening 828. The top wall 814 and the side wall 816 cooperate to form arounded edge or shoulder 840 b at the recessed portion 840. It isfurther understood that the cover 812 of the lid 810 could also have atab formed thereon as shown in the embodiment of FIG. 9.

The moveable element, or disk, 850 is illustrated in FIGS. 23 and 26.The element 850 is rotatably mounted on the support member 837 of thecover 812 such that the support member 837 is received in a portion ofthe element 850. As discussed above, several structures have beendisclosed and other structures are possible wherein the element 850 isrotatably supported with respect to the cover 812. In addition, althoughthe moveable element 850 is illustrated as a disk, and is referred tointerchangeably as a “disk” throughout this description, this is onlyillustrative of the preferred embodiment. The moveable element 850 maytake any of a multitude of forms other than a disk, and the shape of themovable element 850 is not a limitation of the present invention. Forexample, the disk can be ring-shaped as described above in otherembodiments of the invention.

As shown in FIG. 26, the element 850 has an aperture 878, an actuator854 accessible through the slot 830, a projection 852, and anindentation or depression 881. The element 850 has an outer edge 851 anda top wall 856 with an top wall surface 856 a and a center portion 862.A side wall 859 depends from the top wall 856. The top wall 856 has acenter portion 862 extending radially inward from the top wall surface856 a. Preferably, the center portion 862 is recessed such that thecenter portion 862 has a curvilinear configuration when viewed incross-section. The degree of recess or curvature of the center portion862 can vary with the design parameters of the lid 810. Preferably, thedegree of recess of the center portion 862 of the element 850 is similarto the degree of recess of the center portion 836 of the cover 812.Alternatively, if the entire top wall 814 of the cover 812 is in planaralignment, the top wall surface 814 a and the center portion 862 of theelement 850 are also in planar alignment.

The projection 852 extends from a portion of the top wall 856. Theprojection 852 has a peripheral edge 853 that defines the shape of theprojection 852. Preferably, the projection 852 is cooperativelydimensioned with the drink opening 828 such that at least a portion ofthe projection 852 is adapted to be received by, or positioned in, theopening 828. The projection 852 has a projection surface 852 a that ispreferably sloped or angled to facilitate reception of the projection852 by the opening 828. When the projection 852 is completely receivedin the opening 828, the opening 828 is sealed and the lid 810 is in theclosed position shown in FIG. 23. Although the presence of theprojection 852 is preferable, it is not essential to the presentinvention. Alternatively, the element 850 has a generally planar surfacethat is aligned with a surface of the cover 812 proximate the opening828 in a surface-to-surface engagement such that the opening 828 issealed. Such as shown in the above embodiments, the element 850 can havea opening adapted to drain the flowable contents into the container 825.

The actuator 854 is accessible through the slot 830 in the cover 812,and is manipulated to move the element 850 between an open position P2and a closed position P1. As illustrated in FIG. 26, the actuator 854 ispreferably a post, but may take any other form suitable formanipulation. For example, the actuator 854 could be a small projectionor protuberance; a series of smaller projections, bumps, or ridges; orsimply a high-friction surface. The post 854 of the preferred embodimentextends from a portion of the top wall 856. In an alternativeembodiment, the post or actuator 854 may be positioned on the side wall859 of the element 850, and the slot 830 may be correspondinglypositioned on the side wall 816 of the cover 812. The post 854 can haveeither a solid or hollow construction depending upon design parameters.At least a portion of the post 854 is received by the slot 830 andextends past the top wall surface 814 a. Although the configuration anddimensions of the post 854 can vary according to design parameters ofthe lid 810, the post 854 must retain a configuration that permits it tobe accessible through the slot 830. As shown in FIG. 26, the post 854has a catenoid shape. The post 854 can have a gripping portion (notshown) that is adapted to facilitate the engagement of a user's fingerswith the post 854. The gripping portion can be integral to the post 854or it can be a separate element fastened to a portion of the post 854.For example, the gripping portion can be a plastic or rubber elementfastened to the walls of the post 854.

As shown in FIG. 26, the disk 850 has at least one aperture 878. Theaperture 878 has a peripheral edge 880 that defines the shape of theaperture 878. When the aperture 878 is aligned with the drink opening828, a passageway is formed between the element 850 and the cover 812permitting the passage or flow of the flowable substance held by thecontainer 825 through the lid 810. Although the aperture 878 can have avariety of configurations and dimensions, the aperture 878 is preferablycooperatively dimensioned with the drink opening 828. In a preferredembodiment, the aperture 878 is positioned on the disk top wall 856 andspaced a distance from the projection 852. In another preferredembodiment, similar to the embodiment described in FIGS. 15-16, theelement 850 could include two separate apertures, each spaced a distancefrom the projection 852. The aperture 878 may be positioned on the diskside wall 859 if necessary, such as if the drink opening 828 of thecover 812 is positioned on the cover side wall 816. The aperture 878could be formed merely by forming a slot or channel in the peripheraledge 851 of the element 850.

A disk recessed portion 884 is preferably positioned about theprojection 852 and the aperture 878. The degree of recess of the portion884 can vary. Although the recessed portion 884 is shown positioned on aportion of both the disk side wall 859 and the disk top wall 856, therecessed portion 884 can be limited to either the side wall 859 or thetop wall 856. The recessed portion 884 is adapted to be received by aninner surface of the recessed portion 840 of the cover 812 when theelement 850 is positioned proximate the cover 812. The position of therecessed portion 884 of the element 850 is similar to the position ofthe recessed portion 840 of the cover 812.

An indentation 881 is located in the center 862 of the disk top wall856, and is one preferred mechanism for rotatably mounting the disk 850on the support member 837. As discussed, several structures can be usedto rotatably support the element 850 on the cover 812. The indentation881 illustrated in FIG. 26 is cylindrical in shape, and has anindentation edge 883 and an inner side wall 885. Alternatively, theindentation 881 may have a more complex shape, or may simply comprise anaperture. The support member 837 and the indentation 881 arecooperatively dimensioned such that they are in rotational engagementwith each other. Preferably, the support member 837 and the indentation881 engage each other with an interference fit between the inner sidewall 883 of the indentation 881 and the outer side wall 837 b of thesupport member 837, as illustrated in FIG. 27.

Referring to FIG. 23, the element 850 and the cover 812 arecooperatively dimensioned such that the element 850 can be positionedwithin the interior region defined by the cover 812, to comprise an“assembled position,” wherein the element 850 is rotatably mounted onthe support member 837. As further shown in FIGS. 23, 27 and 28, theelement 850 is attached to the support member 837 in such a way that theelement 850 is held in place, while having at least some freedom torotate in either direction. Preferably, as described above, the supportmember 837 and the indentation 881 are cylindrically shaped and engageeach other with an interference fit. Other structures could be added tothe support member 837 and indentation 881 to enhance the rotatableconnection. However, many other mechanisms for rotatably mounting theelement 850 upon the support member 837 exist, and the present inventionis not intended to be limited to any particular mechanism for rotationalengagement between the element 850 and the cover 812. In one alternativeembodiment, the support member 837 contains or comprises a lip or cuspfor holding the disk in place, eliminating the necessity for aninterference fit. In another possible embodiment, the support member 837consists of only an aperture, and the disk contains a cooperativelydimensioned projection that extends through the aperture to support thedisk, rather than an indentation. Furthermore, it is understood that themale/female aspects of the support member 837 and indentation 881 couldbe reversed on the cover 812 and element 850. The key aspect of thepresent invention is not the structure of the mounting mechanism, butthe use of a moveable element rotatably mounted by a support member.

In the assembled position, the actuator 854 is accessible by a userthrough the slot 830. In the preferred embodiment, the element 850 ispositioned proximate the cover 812 such that at least a portion of thepost 854 is received by and extends through the slot 830. In thisconfiguration, the element 850 is positioned beneath the cover 812 suchthat the center portion 836 of the cover 812 is proximate the centerportion 862 of the element 850. The actuator 854 may take one of manyother forms, but regardless of the form of the actuator, it isaccessible through the slot 830.

In the assembled position, the element 850 is movable by rotatingbetween a first, or closed, position and a second, or open, position.The element 850 is moved between the first and second positions P1, P2by manipulation of the actuator 854 by a user. In the first position P1,as shown in FIG. 23, the projection 852 is received by the drink opening828 such that the opening 828 is sealed and the lid 810 is closed. Whenthe opening 828 is sealed, the edge 829 of the opening 828 is infrictional engagement with the projection 852. The top portion of theprojection 852 can extend past the edge 829 of the drink opening 828.This seal prevents the flow of the flowable substance in the container825 through the opening 828, enabling the container 825 and lid 810 tobe moved without risking spillage. Also, in the first position P1, therecessed portion 862 of the element 850 is engaged with the recessedportion 836 of the cover 812. In addition, in the first position P1, theaperture 878 is misaligned or offset from the opening 828.Alternatively, the projection 852 and the opening 828 are in a snap fitengagement wherein each have sufficient structure to enable the snap fitengagement. Other cooperating structures can also be utilized.

In an alternate configuration of the element 850, the projection 852 isomitted (not shown), and the top wall surface 856 is substantially flat.In the first position P1, the flat top wall 856 surface of the element850 is aligned with the opening 828 in a surface-to-surface engagementsuch that the opening 828 is sealed.

In the second position P2, the aperture 878 is aligned with the drinkopening 828 to form a passageway between the element 850 and the cover812 wherein the lid 810 is open, as illustrated in FIG. 28. Thepassageway permits the passage or flow of the flowable substance held bythe container 825 through the lid 810. When the lid 810 is in the secondposition P2, at least a portion of the aperture 878 is aligned with atleast a portion of the edge 829 of the drink opening 828. In addition,in the second position P2, the projection 852 is misaligned with, oroffset from, the opening 828. When the aperture 878 is partially alignedwith the drink opening 828, the passageway remains but its dimensionsare reduced. When the aperture 878 is completely misaligned with thedrink opening 828, the passageway is eliminated. When the aperture 878is completely misaligned with the drink opening 828 and the projection852 is received in the opening 828, the opening 828 is sealed and thelid 810 is in the first position, P1. Alternatively, if no projection ispresent, the element 850 is returned to the first position P1 whereinthe aperture 878 is completely misaligned with the drink opening 828,and the opening 828 is sealed.

A user can move the element 850 between the first position P1 and thesecond position P2 by manipulating the actuator 854. In the preferredembodiment, this is done by grasping and actuating or manipulating thepost 854 between the first end 830 a of the slot 830 and the second end830 b of the slot 830. Referring to FIG. 23, when the post 854 isproximate the first end 830 a, the element 850 is in the first positionP1. Conversely, referring to FIG. 28, when the post 854 is proximate thesecond end 830 b, the element 850 is in the second position P2. The post854 can be located in a number of positions between the first and secondends, and as a result, the projection 852 can be misaligned with theopening to varying degrees.

As explained above, the element 850 can have a first and secondaperture, wherein the apertures are positioned about the projection suchas shown by the disk in FIG. 16. In this configuration, the disk can berotated in either a clockwise or counter-clockwise direction to move thedisk between a first position, in which the lid is closed, and a secondposition and a third position, in which the lid is open. In thisposition, the actuator is located close to the center of the slot,rather than at either end. When the disk is in the first position,rotating the disk in the clockwise direction brings the first apertureinto alignment with the opening. Similarly, when the disk is in thefirst position, rotating the disk in the counter-clockwise directionmoves the disk to the third position, bringing the second aperture intoalignment with the opening. This feature further increases theflexibility and value of the lid.

Several additional embodiments of the lid of the present invention arefurther disclosed herein and described below.

FIGS. 29-36 disclose another embodiment of the lid, generally designatedwith the reference numeral 1010. The lid 1010 generally includes a cover1012 and a moveable element 1050.

The cover 1012 has a top wall 1014 and a side wall 1016 depending fromthe top wall 1014. The top wall 1014 further has an opening 1028 and aslot 1030. The cover 1012 further has a mounting portion 1022 connectedto the side wall 1016 that is configured to mount to a container or cupas shown in FIG. 29. The top wall 1014 further has a support member 1034generally at a central portion 1017 of the top wall 1014. In onepreferred embodiment, the support member 1034 is in the form of adepending post.

In this embodiment, the top wall 1014 of the cover 1012 is bi-leveled,as further shown in FIGS. 29 and 31. The top wall 1014 has an upperlevel 1013 and a lower level 1015. The relatively annular upper level1013 is connected to the relatively planar lower level 1015 by thetapering central portion 1017. This configuration provides a means ofclearance for a nose of a user drinking from the container. The slot1030 is located on the lower level 1015 and the opening 1028 is locatedon the upper level 1013. As further shown in FIGS. 29 and 31, the cover1012 further includes a position indicator 1064 located on the top wall1014 generally at the central portion 1017. The position indicator 1064is described in greater detail below.

As further shown in FIGS. 29-33, the moveable element 1050 is rotatablymounted on the cover 1012. The moveable element 1050 is generallydisk-shaped and has a projection 1052, an aperture 1078 (preferably afirst aperture 1078 and a second aperture 1078), and an actuator 1054.The moveable element 1050 further has a central indentation 1081 thatcooperates with the support member 1034 of the cover 1012 as describedin greater detail below. Additionally, the moveable element 1050 iscooperatively dimensioned to accommodate the bi-leveled top wall 1014 ofthe cover 1012. Like the cover 1012, the moveable element 1050 has a topwall 1056 that has a relatively annular upper level 1055 and arelatively planar lower level 1057 connected by a tapering centralportion 1059.

As shown in FIGS. 29, 30 and 33, the moveable element 1050 is rotatablymounted on the cover 1012. Preferably, the moveable element 1050 ismounted on the support member 1034 wherein the indentation 1081 of themoveable element 1050 is received by the support member 1034 of thecover 1012. The indentation 1081 is dimensioned so as to fit around thesupport member 1034. However, the moveable element 1050 may be rotatablymounted on the support member 1034 by any other known means as well asthose methods described herein. Once properly mounted, the actuator 1054is received by the slot 1030. In the assembled lid 1010, the actuator1054 is accessible through the slot 1030.

The moveable element 1050 is moveable between a first position and asecond position by rotation of the moveable element 1050 about thesupport member 1034. FIGS. 29 and 30 show the lid 1010 in the firstposition defining a closed position. In the closed position, theprojection 1052 is positioned within the opening 1028. The apertures1078 are misaligned with the opening 1028. Also, the position indicator1064 indicates to the user that the lid 1010 is in the closed position.The indicator 1064 is aligned with the actuator 1054 to indicate theclosed position. As shown in FIG. 34, the moveable element 1054 isrotatably moveable to the second position such as by a user manipulatingthe actuator 1054. The second position defines an open position whereinthe aperture 1078 is aligned with the opening 1028 wherein a flowablesubstance can pass therethrough. In this position, the actuator 1054 ispositioned to one end of the slot 1030 wherein the actuator 1054 ismisaligned with the position indicator 1064. As further shown in FIG.35, because the moveable element 1054 has a second aperture 1078, theactuator 1054 can be rotated in an opposite direction than as shown inFIG. 34, wherein the actuator 1054 is rotated to an opposite side of theslot 1034. In this position, the other aperture 1078 is aligned with theopening 1028. Thus, the moveable element 1054 can be rotated in either aclockwise direction or a counterclockwise direction to place themoveable element 1054 in the second, open position.

It is understood that the position indicator 1064 and the actuator 1054have first and second positional relationships with respect to oneanother when the lid is in the closed and open positions. In the presentembodiment, the closed position is indicated by the position indicator1064 being aligned with the actuator 1054. The open position isindicated by misalignment of the indicator 1064 and the actuator 1054.It is understood, however, that this configuration could be reversedwherein an aligned configuration could indicate an open position and amisalignment could indicate a closed position. It is further understoodthat the indicator 1064 may take other forms.

FIGS. 37-43 disclose another embodiment of the lid of the presentinvention. The lid 1110 generally includes a cover 1112 and a moveableelement 1150.

As further shown in FIGS. 37-39, the cover 1112 has a top wall 1114 anda depending side wall 1116. The cover 1112 further has an opening 1128,a slot 1130, a mounting portion 1122, and a support member 1134. Theopening 1128 is preferably in the top wall 1114 but could be in otherlocations such as the side wall 1116. The support member 1134 protrudes,rather than depends, from the top wall 1114, and the support member 1134is located near an edge 1160 of the top wall 1114, rather than in thecenter, as illustrated in FIGS. 37-43. As described in greater detailbelow, the moveable element 1150 is pivotally mounted on the supportmember 1134.

Preferably, the support member 1134 for this embodiment is a protrusionfrom the top wall 1114, which receives a member projecting from themoveable element 1150. Alternately, the support member 1134 can have anyone of the many possible configurations already discussed herein. Theslot 1130 in the top wall 1114 provides access to an actuator associatedwith the moveable element 1150 and allows the moveable element 1150 topivot between the open and closed positions. As further shown in FIG.37, the cover 1112 may have indicators for additives that may beincluded with flowable contents contained in the container, generallydesignated “S,” (sugar) and “C” (cream). Other indicators, such as “D”(decaf) may also be included.

As shown in FIG. 40, the moveable element 1150 of the lid 1110 includesa knob 1151 and an actuator 1154 affixed to an appendage 1148. Theappendage 1148 is an elongated finger-type member rather than beingdisk-shaped. Preferably, the moveable element 1150 has no aperture, andopens and closes the lid 1110 by blocking or moving away from theopening 1128, creating an open position and a closed position.Alternately, the moveable element 1150 contains an aperture (not shown).The moveable element 1150 can also contain a projection 1152 for sealingthe opening 1128 when the moveable element 1150 is in the closedposition. The moveable element 1150 is pivotably mounted on the supportmember 1134. Preferably, and as can be appreciated from FIGS. 41-43, theknob 1151 fits inside the support member 1134, forming an interferencefit, allowing the moveable element 1150 to pivot between the open andclosed positions. Nearly any means discussed herein of rotatablymounting a moveable element 1150 on a support member 1134 will functionto pivotably mount a moveable element 1150 as well. Thus, a wide rangeof mounting configurations are available.

As shown in FIGS. 41-43, the lid 1110 is moveable between an openposition and a closed position by the user manipulating the actuator1154, which is accessible through the slot 1130. The appendage 1148 ofthe moveable element 1150 is preferably a generally elongated member, asillustrated in FIG. 40. In the closed position, illustrated in FIGS. 37and 38, the tip of the appendage 1148 obstructs the opening 1128. Theactuator 1154 is positioned at an end of the slot generally towards acentral portion of the cover 1112. In the open position, illustrated inFIGS. 42 and 43, the appendage 1148 is pivoted away from the opening1128, allowing a flowable substance to pass through. A user forces theactuator 1154 to an opposite end of the slot 1130 generally towards anouter edge of the container 1112. Thus, the actuator 1154 moves to andfrom a center portion of the cover 1112 or to and from an outer edge ofthe cover 1112. This movement pivots the moveable element 1150 about thesupport member 1134. The slot 1130 of this embodiment is fairly short inlength, since the proximity of the actuator 1154 to the point ofrotation requires a small movement for operation. The movement andlocation of the actuator 1154 of this embodiment favors the use of atrigger-shaped actuator 1154, rather than the standard post describedabove. It is understood that the location of the support member 1134could vary to accommodate different shapes of pivoting moveable members1150.

FIGS. 44-47 disclose another embodiment of the lid of the presentinvention, generally designated with the reference numeral 1210. The lid1210 generally includes a cover 1212 and a moveable element 1250.

The cover 1212 has an opening 1228, a slot 1230, a mounting portion1218, and a support member 1234 depending from a center of the top wall1214. The top wall 1214 has a central recessed portion. The supportmember 1234 is generally in the form of a post. As described in greaterdetail below, the moveable element 1250 is rotatably mounted on thesupport member 1234. The slot 1230 is a large slot 1230 and extendsabout a half of the circumference of the cover 1212, and further extendsto both the top wall 1214 and sidewall 1216 of the cover 1212. Further,the cover 1212 contains a stop 1270 (FIG. 47) that constrains therotation of the moveable element 1250 as described in greater detailbelow.

As shown in FIGS. 46-47, the moveable element 1250 has a centralrecessed portion that corresponds to the central recessed portion of thecover 1212. The moveable element 1250 has an indentation 1281 thatdefines a recess. As explained in greater detail below, the indentation1281 receives the support member 1234 of the cover 1212 for rotatablesupport. The moveable element 1250 further has an aperture 1278 and aprojection 1252 on each side of the aperture 1278. The aperture 1278 andprojections are located on a frontal segment of the moveable element1250. Finally, the moveable element 1250 has an actuator 1254 accessiblethrough the slot 1230. The actuator 1254 extends around a circumferenceof the element and is spaced from the frontal segment. Generally, themoveable element 1250 in contoured to correspond in shape with theinside structure of the cover 1212.

The actuator 1254 defines an extended side wall 1261 opposite theaperture 1278. The actuator 1254 has recesses 1269 on the side wall 1261to form a gripping element 1268 to enhance the grippability of theactuator 1254. To accommodate this extended side wall 1261, the slot1230 in the cover 1212 extends through a portion of the cover top wall1214 and through most of the height of the cover side wall 1216,stretching for nearly half the circumference of the cover 1212. Theconfiguration of this embodiment of the present invention provides alarge area of access to the actuator 1254.

As shown in FIGS. 46 and 47, the moveable element 1250 is preferablyrotatably supported by the cover 1212. The moveable element 1250 ispositioned within the cover 1212 wherein the indentation 1281 receivesthe support member 1234. The indentation 1281 is dimensioned so as tofit around the support member 1234. However, the moveable element 1250can be rotatably mounted on the support member 1234 by any meansdescribed herein. As discussed and disclosed, the overall contour of themoveable element 1250 generally corresponds to the inner surface of thecover 1212.

The moveable element 1250 of the lid 1210 illustrated in FIGS. 44-47 ismoveable between an open position and a closed position. As shown inFIG. 45, when the aperture 1278 that is cooperatively dimensioned withthe opening 1228, is aligned with the opening 1228 on the cover 1212,the lid 1210 is in the “open” position. As discussed, the projections1252 are located on either side of the aperture 1278. When a userengages the actuator 1254 and rotates the moveable element 1250, one ofthe projections 1252 is aligned with the opening 1228, wherein theopening 1228 is obstructed and the lid 1210 is in the closed position.The gripping element 1268 of the actuator 1254 assists the user inrotating the moveable element 1250. It is understood that the moveableelement 1250 can be rotated in an opposite direction wherein the otherprojection 1252 will be aligned with the opening 1228 to also create aclosed lid position. Thus, the lid 1210 has two closed positions and oneopen position. Accordingly, as illustrated and described, the lid 1210can be moved from one closed position, where the aperture 1278 islocated to the left of the opening 1228, to the open position, and tothe other closed position, where the aperture 1278 is located to theright of the opening 1228, by rotation.

As can be understood by FIGS. 44-47, the slot 1230 does not constrainthe rotation of the moveable element 1250, because the actuator 1254does not project through the slot 1230. Accordingly, the lid 1210 has atleast one stop 1270 to constrain rotation of the moveable element 1250.As shown in FIGS. 46 and 47, the stop 1270 preferably comprises a tab1271 on the inner surface 1232 of the cover 1212. The stop 1270 shown inFIGS. 46-47 is aligned with the center of the opening 1228, and themoveable element 1250 has a notch 1272 aligned with the center of theaperture 1278, such that the tab 1271 will sit within the notch 1272,partially constraining the rotation of the moveable element 1250, whenthe aperture 1278 and the opening 1228 are aligned. Thus, the lid 1210will be “locked” in the open position, and small forces exerted on thelid 1210, resulting from jostling or bumping, will not move the lid 1210from the open position. The lid 1210 may additionally or alternatelyinclude stops (not shown) to the left and/or right of the opening 1228to create other partially constrained (“locked”) positions, or tototally constrain rotation of the moveable element 1250 beyond certainpoints of rotation. Alternately, a stop 1270 may both partially andtotally constrain rotation of the moveable element 1250, as may bedesired.

As illustrated in FIGS. 5-8, the moveable element used to seal and openthe lid may be an overlay (e.g. the overlay 250) rather than beingpositioned on the interior of the lid. However, other means of mountingthe overlay on the cover exist beyond those previously illustrated anddescribed. FIGS. 48-58 disclose additional embodiments utilizingrotatable overlay elements. It will be understood that the severalembodiments share common features that will be designated with similarreference numerals. The lid disclosed in FIGS. 48-51, generallydesignated with the reference numeral 1310, will be described in greaterdetail. As there are many structural similarities, this detaileddescription will also apply to the other embodiments such as in FIGS.52-53 (utilizing “1310 a” reference designations), FIGS. 54-55(utilizing “1310 b” reference designations) and FIGS. 56-58 (utilizing“1310 c” reference designations). Other distinguishing features of eachembodiment will also be described.

As shown in FIGS. 48-51, the lid 1310 generally includes a cover 1312and a moveable element in the form of a rotatable overlay 1350. Asexplained in greater detail below, the overlay 1350 is rotatablysupported on a track of the cover 1312.

The cover 1312 generally has a top wall 1314, a side wall 1316 dependingfrom the top wall 1314, a mounting portion 1322 at the base of the sidewall 1316 and an opening 1328. The top wall 1314 also has a recessedcentral portion 1336. The cover 1312 further defines a track 1342 thatrotatably supports the overlay 1350. As shown in FIGS. 48 and 51, thetrack 1342 is preferably annular, and most preferably comprises anannular cusp 1343 extending around the entire circumference of the cover1312. The cusp 1343 is positioned on the outside of the side wall 1316and preferably extends from a portion of the mounting portion 1322. Thetrack 1342 is defined generally between the cusp 1343 and a portion ofthe mounting portion 1322.

The overlay 1350 generally has a similar contoured shape as the cover1312. As shown in FIGS. 48 and 50, the overlay 1350 has a top wall 1356and a depending side wall 1359. The overlay 1350 has a recessed centralportion 1362 cooperatively dimensioned with the recessed central portion1336 of the cover 1312. Additionally, the overlay 1350 preferably has atleast one aperture 1378, which is aligned with the opening 1328 in theopen position, providing access to the opening 1328. The aperture 1378is preferably a cut-away portion 1378 of the overlay 1350, but isalternately a small hole or slot in the overlay 1350. Preferably, theoverlay 1350 has two apertures 1378 that create a finger 1367therebetween. The finger 1367 is adapted to seal the opening 1328 in theclosed position. In one embodiment, the finger 1367 is connected to theoverlay 1350 at both ends, as illustrated in FIGS. 48-51. The overlay1350 further has an annular flange 1346 extending from the side wall1359 of the overlay 1350. The annular flange 1346 is dimensioned to fitin the track 1342 as described in greater detail below.

Further, the overlay 1350 preferably has an actuator 1368 in the form ofa gripping element 1368 to facilitate gripping and manipulating theoverlay 1350, such as one or more ridges. Finally, the overlay 1350preferably includes a projection 1352, which projects from the bottomsurface of the overlay 1350, and preferably at the finger 1367. Theprojection 1352 fits within the opening 1328 when the lid 1310 is in theclosed position, sealing the opening 1328.

As can be appreciated from FIGS. 50-51, the overlay 1350 fits over thecover 1312. As discussed, the overlay 1350 is rotatably supported in thetrack 1342 of the cover 1312. The annular flange 1346 on the overlay1350 is received in the track 1342. The cusp 1343 engages the flange1346 as shown in FIG. 51. The cusp 1343 holds the overlay 1350 close tothe top of the lid 1310 while allowing it the freedom to rotate relativeto the cover 1312.

Notably, while the track 1342 for mounting the overlay 1350 ispreferably annular, the structure or structures creating the track 1342need not be. For example, the annular track 1342 may alternatelycomprise several intermittently spaced cusps (not shown) around thecircumference of the sidewall, the flange 1346 being interlocked withthe cusps. Similarly, the track 1342 may only extend for a portion ofthe perimeter of the cover 1312. Finally, the track 1342 need not beannular, although an annular track 1342 is preferable, and anyconfiguration of the track 1342 allowing the overlay 1350 to berotatably mounted on the cover 1312 is effective. Still otherembodiments and configurations are possible.

As with the previous embodiments, the lid 1310 has a closed position andan open position. The closed position is shown in FIG. 48 wherein thefinger 1367 is proximate and covering the opening 1328. Furthermore, theprojection 1352 is received in the opening 1328. As shown in FIG. 49, auser rotates the overlay 1350 such as by engaging the actuator 1368wherein the aperture 1378 is generally aligned with the opening 1328 toallow a flowable substance to flow through the opening 1328. It isunderstood that a user could rotate the overlay 1350 in an oppositedirection wherein the other aperture is aligned with the opening 1328.When moving between the open and closed positions, the overlay 1350rides in the track 1342 of the cover 1312.

FIGS. 52-53 disclose another embodiment of the lid using a rotatableoverlay, generally designated with the reference numeral 1310 a. The lid1310 a has similar features to the lid 1310 of FIGS. 48-51. As shown inFIGS. 52 and 53, the lid 1310 a has a recessed central portion. Theoverlay 1350 a has an open central portion 1347 and preferably has agenerally toroidal shape, i.e. a three-dimensional ring wherein therecessed central portion of the cover 1312 a. The cover 1312 has a topwall 1314 a that defines an additional annular track. The overlay 1350 aalso has a top wall 1356 a that corresponds to the top wall 1314 a ofthe cover 1312 a. The top wall 1356 a is also rotatably supported by thetop wall 1356 a of the cover 1312 a, as the overlay 1350 a rides alongthe annular track defined by the top wall 1314 a of the cover 1312 a.The overlay 1350 a also has apertures 1378 a separated by the finger1367 a. In this embodiment, the finger 1367 a extends upwards from abase of the overlay 1350 a and does not extend across the centralportion of the overlay 1350 a. The finger 1367 a has a distal end thatrides over the top wall 1314 a of the cover 1312.

FIG. 52 shows the open position wherein the overlay 1350 a is rotatedsuch that the finger 1367 is spaced from the opening 1328 a and one ofthe apertures 1378 a is aligned with the opening 1328 a. In thisposition, the side wall of the cover 1312 has a “close” indicia thereonindicating a direction of rotation for the overlay 1350 a to close thelid 1310 a. FIG. 53 shows the overlay 1350 a rotated such that thefinger 1367 obstructs the opening 1328 a. In this position, the sidewall of the cover 1312 has an “open” indicia thereon indicating adirection of rotation for the overlay 1350 a to open the lid 1310 a.

FIGS. 54-55 show another embodiment of the lid utilizing a rotatableoverlay, the lid being generally designated with the reference numeral1310 b. The structure is similar as described above. The overlay 1350 bhas larger ridges 1368 b than in the previous embodiments. The overlay1350 b has cut-away portions or apertures 1378 b wherein the finger 1367b extends therebetween. As shown in FIGS. 54-55, the cover 1312 bincludes one or more stops 1370 for constraining rotation of the overlay1350 b. The stops 1370 may partially constrain rotation of the overlay1350 b, by creating one or more “locked” positions, or may totallyconstrain rotation of the overlay 1350 b, or may do both. For example,the stops 1370 of the lid 1310 b illustrated in FIGS. 54-55 totallyconstrain rotation of the overlay 1350 b in one direction. Many otherstop configurations are possible to achieve the same effect.

FIG. 54 shows the lid in a closed position wherein the finger 1367 bobstructs the opening 1328 b. FIG. 55 shows the overlay 1350 b rotatedwherein the lid is in the open position. In this position, an edgeportion of the overlay 1350 b engages the stop 1370 to prevent furtherrotation of the overlay 1350 b. It is understood that the other stop1370 is used to engage another edge portion of the overlay 1350 b if theoverlay 1350 b is rotated in an opposite direction.

FIGS. 56-58 show yet another embodiment utilizing a rotatable overlay,the lid being designated with the reference numeral 1310 c. In thisembodiment, the track 1342 c is located in the top wall 1314 c of thecover 1312 c, rather than in the side wall 1316 c. The overlay 1350 c isannular and generally ring-shaped. The overlay 1350 c has an aperture1378 c to expose the opening 1328 c, and rotates while mounted on theannular track 1342 c in the top wall 1314 c.
